增强移动通信装置的信号收发功能的无线电信号收发装置 Radio signal transceiving device for enhancing signal transceiving function of mobile communication device

技术领域technical field

本发明指一种可增强一移动通信装置的信号收发功能的无线电信号收发装置，尤其指一种通过转换切换开关的操作，使所接收及传输的信号不通过滤波器的处理，以增加信号的强度，从而增加紧急状况下信号接收及传输能力的无线电信号收发装置。The present invention refers to a radio signal transceiving device capable of enhancing the signal transceiving function of a mobile communication device, especially to a radio signal transmitting and receiving device through the operation of a switching switch, so that the received and transmitted signals do not pass through the processing of the filter, so as to increase the signal efficiency. Intensity, thereby increasing the radio signal receiving and transmitting capability in emergency situations.

背景技术Background technique

随着无线通信技术快速且高度的发展，轻巧便利的移动电话已大大改变人与人的沟通方式。通过移动电话，人们可随时随地进行信息交换，尤其当发生紧急状况时，使用者可通过移动电话适时与外界联系，达到救人救命的目的。然而，公知移动电话的传输、接收信号情形受限于与最近基地台的距离，且易受地形、地物等影响。因此，若使用者处于山区或较偏远的地方，基地台的信号较微弱，甚至无法与移动电话连接，使得使用者无法成功与外界取得联系，此时若遭遇紧急状况(如发生山难、遇到强劫等情形)，可能因此丧失救人先机。With the rapid and high-level development of wireless communication technology, light and convenient mobile phones have greatly changed the way people communicate with each other. Through the mobile phone, people can exchange information anytime and anywhere, especially when an emergency occurs, the user can timely contact the outside world through the mobile phone to achieve the purpose of saving lives. However, known mobile phone transmission and reception conditions are limited by the distance from the nearest base station, and are easily affected by terrain, ground objects, and the like. Therefore, if the user is in a mountainous area or a relatively remote place, the signal of the base station is relatively weak, and even the mobile phone cannot be connected, so that the user cannot successfully contact the outside world. to robbery, etc.), may thus lose the opportunity to save lives.

要解决上述问题，可增加基地台的数量或改善移动电话的传输、接收能力。前者会增加系统业者的负担，后者可能使得移动电话无法通过认证或干扰其它电子装置。举例来说，请参考图1，图1为公知一收发装置10的示意图。收发装置10可用于一移动通信装置，如移动电话、个人数字助理等电子装置，其包含有一天线100、一发射接收开关102、一表面声波滤波器104、一低噪声放大器106、一降频模块108、一功率放大器110、一升频模块112及一信号处理模块114。发射接收开关102由一切换开关115及滤波器116、118所组成，在接接收信号号时，切换开关115会根据一控制信号Vc将天线100切换电连接到滤波器116，则天线100所接收的信号会通过滤波器116及表面声波滤波器104以去除大部份的干扰，再经过低噪声放大器106将信号放大，最后借助降频模块108将信号降至基频并传送至信号处理模块114以输出相关信号(如语音、简信、图像等)。相反地，在传输信号时，天线100被切换电连接到滤波器118，信号处理模块114输出的基频信号通过升频模块112将频率升至射频，并经由功率放大器110放大信号能量，再由滤波器118去除不必要的干扰信号，以避免干扰其它电器用品，最后由天线发射信号至空中。To solve the above problems, the number of base stations can be increased or the transmission and reception capabilities of mobile phones can be improved. The former will increase the burden on the system operator, and the latter may make the mobile phone unable to pass the authentication or interfere with other electronic devices. For example, please refer to FIG. 1 , which is a schematic diagram of a known transceiver device 10 . The transceiver device 10 can be used in a mobile communication device, such as a mobile phone, a personal digital assistant and other electronic devices, which include an antenna 100, a transmitting and receiving switch 102, a surface acoustic wave filter 104, a low noise amplifier 106, and a frequency reduction module 108 . A power amplifier 110 , an up-conversion module 112 and a signal processing module 114 . The transmitting and receiving switch 102 is composed of a switch 115 and filters 116 and 118. When receiving a signal signal, the switch 115 will switch and electrically connect the antenna 100 to the filter 116 according to a control signal Vc, and the antenna 100 receives The signal will pass through the filter 116 and the surface acoustic wave filter 104 to remove most of the interference, then pass through the low noise amplifier 106 to amplify the signal, and finally reduce the signal to the base frequency by the frequency reduction module 108 and send it to the signal processing module 114 To output related signals (such as voice, short message, image, etc.). On the contrary, when transmitting a signal, the antenna 100 is switched and electrically connected to the filter 118, and the baseband signal output by the signal processing module 114 is raised to a radio frequency by the up-frequency module 112, and the signal energy is amplified by the power amplifier 110, and then the The filter 118 removes unnecessary interference signals to avoid interfering with other electrical appliances, and finally transmits signals to the air through the antenna.

因此，若要加强收发装置10的收发功能，可通过增加低噪声放大器106及功率放大器110的增益。然而，增加低噪声放大器106的增益会使得所接收的信号的噪声部分被放大，因此会降低信号的品质，而增加功率放大器110的增益不仅会影响其它电器用品，亦可能无法通过法律规范。Therefore, if the transceiver function of the transceiver device 10 is to be enhanced, the gain of the low noise amplifier 106 and the power amplifier 110 can be increased. However, increasing the gain of the low noise amplifier 106 will amplify the noise part of the received signal, thus degrading the quality of the signal, and increasing the gain of the power amplifier 110 will not only affect other electrical appliances, but may also fail to pass legal regulations.

具体实施方式Detailed ways

请参考图2，图2为本发明第一实施例无线电信号接收装置20的示意图。无线电信号接收装置20可增强一移动通信装置的信号接收功能，该移动通信装置可以是移动电话、个人数字助理等电子装置。无线电信号接收装置20包含有一接收天线200、一低噪声放大器202、一降频电路204、一信号处理电路206、一滤波器208、一第一切换开关210、一第二切换开关212及一控制电路214。低噪声放大器202包含有一第一端216及一第二端218；第一切换开关210包含有一第一端220、一第二端222及一第三端224；第二切换开关212包含有一第一端226、一第二端228，及一第三端230。接收天线200可接收无线电信号并输出至第一切换开关210的第一端220，滤波器208可过滤噪声，低噪声放大器202可将其第一端216所接收的信号放大后由第二端218输出，降频电路204可将低噪声放大器202输出的信号的频率降至一预设范围。另外，第一切换开关210可根据控制电路214输出的一控制信号V1_SW1切换电连接到第二端222或第三端224，而第二切换开关212则可根据控制电路214输出的一控制信号V1_SW2切换电连接到第二端228或第三端230。在无线电信号接收装置20中，滤波器208可过滤噪声，因此滤波器208或多或少会降低信号强度。本发明可通过控制电路214，当特定情形(如发生危急状况，或信号微弱)时，将接收天线200所接收的信号不经由滤波器208过滤噪声，以加强信号强度。关于无线电信号接收装置20的详细操作，请见以下说明。Please refer to FIG. 2 , which is a schematic diagram of a radio signal receiving device 20 according to a first embodiment of the present invention. The radio signal receiving device 20 can enhance the signal receiving function of a mobile communication device, and the mobile communication device can be an electronic device such as a mobile phone or a personal digital assistant. The radio signal receiving device 20 includes a receiving antenna 200, a low noise amplifier 202, a frequency reduction circuit 204, a signal processing circuit 206, a filter 208, a first switch 210, a second switch 212 and a control circuit 214. The low noise amplifier 202 includes a first end 216 and a second end 218; the first switching switch 210 includes a first end 220, a second end 222 and a third end 224; the second switching switch 212 includes a first end 226 , a second end 228 , and a third end 230 . The receiving antenna 200 can receive the radio signal and output it to the first end 220 of the first switch 210, the filter 208 can filter the noise, and the low noise amplifier 202 can amplify the signal received by the first end 216 and transmit it to the second end 218 Output, the down-frequency circuit 204 can reduce the frequency of the signal output by the low-noise amplifier 202 to a preset range. In addition, the first switch 210 can be switched and electrically connected to the second terminal 222 or the third terminal 224 according to a control signal V1_SW1 output by the control circuit 214, and the second switch 212 can be switched according to a control signal V1_SW2 output by the control circuit 214. The switch is electrically connected to either the second terminal 228 or the third terminal 230 . In the radio signal receiving device 20, the filter 208 can filter noise, so the filter 208 can reduce the signal strength more or less. In the present invention, through the control circuit 214, when a specific situation (such as an emergency situation occurs or the signal is weak), the signal received by the receiving antenna 200 is not filtered by the filter 208 to enhance the signal strength. For the detailed operation of the radio signal receiving device 20, please refer to the following description.

在一般使用状况之下，控制电路214通过控制信号V1_SW1及V1_SW2，将第一切换开关210的第一端220切换电连接到第一切换开关210的第三端224，并将第二切换开关212的第一端226切换电连接到第二切换开关212的第三端230。如此一来，接收天线200所接收的信号通过第一切换开关210的第一端220及第三端224后，由滤波器208过滤掉不必要的噪声，再通过第二切换开关212的第三端230及第一端226，输出至低噪声放大器202的第一端216。低噪声放大器202可将第一端216所接收的信号适度放大后，由第二端218输出至降频电路204。降频电路204将所接收的信号的频率降至一预设范围后输出至信号处理电路206，以进行后续信号处理。Under normal use conditions, the control circuit 214 switches and electrically connects the first terminal 220 of the first switch 210 to the third terminal 224 of the first switch 210 through the control signals V1_SW1 and V1_SW2, and connects the second switch 212 The first terminal 226 of the switch is electrically connected to the third terminal 230 of the second switch 212 . In this way, after the signal received by the receiving antenna 200 passes through the first end 220 and the third end 224 of the first switch 210, the unnecessary noise is filtered out by the filter 208, and then passes through the third end of the second switch 212. The terminal 230 and the first terminal 226 are output to the first terminal 216 of the low noise amplifier 202 . The low noise amplifier 202 can properly amplify the signal received by the first end 216 and then output it to the frequency reduction circuit 204 through the second end 218 . The down-frequency circuit 204 reduces the frequency of the received signal to a preset range and outputs it to the signal processing circuit 206 for subsequent signal processing.

另一方面，当欲增强信号接收功能时，则利用控制电路214通过控制信号V1_SW1及V1_SW2，将第一切换开关210的第一端220切换电连接到第一切换开关210的第二端222，并将第二切换开关212的第一端226切换电连接到第二切换开关212的第二端228。如此一来，接收天线200所接收的信号通过第一切换开关210的第一端220及第二端222后，直接传送至第二切换开关212的第二端228及第一端226，亦即接收天线200所接收的信号可直接传送至低噪声放大器202的第一端216。然后，低噪声放大器202将第一端216所接收的信号适度放大后，由第二端218输出至降频电路204。降频电路204将所接收的信号的频率降至一预设范围后输出至信号处理电路206，以进行后续信号处理。换句话说，控制电路214可将接收天线200所接收的信号不经过滤波器208的处理，而直接传送至低噪声放大器202的第一端216进行后续信号处理。因此，当使用者遭遇紧急状况(如发生山难)时，本发明无线电信号接收装置20可加强移动通信装置的信号接收能力。On the other hand, when it is desired to enhance the signal receiving function, the control circuit 214 is used to switch and electrically connect the first terminal 220 of the first switch 210 to the second terminal 222 of the first switch 210 through the control signals V1_SW1 and V1_SW2, And switch and electrically connect the first terminal 226 of the second switch 212 to the second terminal 228 of the second switch 212 . In this way, the signal received by the receiving antenna 200 is directly transmitted to the second end 228 and the first end 226 of the second switch 212 after passing through the first end 220 and the second end 222 of the first switch 210, that is, The signal received by the receiving antenna 200 can be directly transmitted to the first end 216 of the LNA 202 . Then, the low noise amplifier 202 appropriately amplifies the signal received by the first end 216 , and outputs the signal to the down-frequency circuit 204 through the second end 218 . The down-frequency circuit 204 reduces the frequency of the received signal to a preset range and outputs it to the signal processing circuit 206 for subsequent signal processing. In other words, the control circuit 214 can directly transmit the signal received by the receiving antenna 200 to the first end 216 of the low noise amplifier 202 for subsequent signal processing without being processed by the filter 208 . Therefore, when the user encounters an emergency (such as a mountain disaster), the radio signal receiving device 20 of the present invention can enhance the signal receiving capability of the mobile communication device.

The frequency up-conversion circuit 304 can increase the frequency of the signal output by the signal processing circuit 306 to a preset range, and then output the signal to the second end 318 of the power amplifier 302, and the power amplifier 302 can convert the signal received by the second end 318 The amplified power is output by the first end 316, the filter 308 can filter the noise, and the transmission antenna 300 can transmit the signal output by the first end 320 of the first switch 310 into the air through radio. In addition, the first switch 310 can be electrically connected to the second terminal 322 or the third terminal 324 according to a control signal V2_SW1 output by the control circuit 314, and the second switch 312 can be switched according to a control signal V2_SW2 output by the control circuit 314. The switch is electrically connected to either the second terminal 328 or the third terminal 330 . In the radio signal transmission device 30, the filter 308 can filter noise, so the filter 308 can reduce the signal strength more or less. In the present invention, the control circuit 314 can be used to directly output the signal output by the power amplifier 302 from the transmission antenna 300 without filtering the noise by the filter 308 in a specific situation (such as an emergency situation), so as to enhance the signal strength. For the detailed operation of the radio signal transmission device 30, please refer to the following description.

在一般传输情形下，控制电路314通过控制信号V2_SW1及V2_SW2，将第一切换开关310的第一端320切换电连接到第一切换开关310的第三端324，并将第二切换开关312的第一端326切换电连接到第二切换开关312的第三端330。如此一来，信号处理电路306将欲传的信号通过升频电路304将信号频率提升至射频，再通过功率放大器302将信号的功率放大。功率放大器302输出的信号通过第二切换开关312的第一端326及第三端330后，由滤波器308过滤掉不必要的噪声，再通过第一切换开关310的第三端324及第一端320，输出至传输天线300，从而通过无线电方式发射信号。In general transmission situations, the control circuit 314 switches and electrically connects the first terminal 320 of the first switch 310 to the third terminal 324 of the first switch 310 through the control signals V2_SW1 and V2_SW2, and connects the terminal 324 of the second switch 312 to The first end 326 is switched and electrically connected to the third end 330 of the second toggle switch 312 . In this way, the signal processing circuit 306 increases the frequency of the signal to be transmitted to a radio frequency through the frequency up-converting circuit 304 , and then amplifies the power of the signal through the power amplifier 302 . After the signal output by the power amplifier 302 passes through the first terminal 326 and the third terminal 330 of the second switch 312, the unnecessary noise is filtered out by the filter 308, and then passes through the third terminal 324 and the first terminal 324 of the first switch 310. The terminal 320 is output to the transmission antenna 300, so as to transmit the signal by radio.

另一方面，当使用者遭遇紧急状况(如发生山难)，而欲加强信号传输功能时，则控制电路314通过控制信号V2_SW1及V2_SW2，将第一切换开关310的第一端320切换电连接到第一切换开关310的第二端322，并将第二切换开关312的第一端326切换电连接到第二切换开关312的第二端328。如此一来，功率放大器302输出的信号，通过第二切换开关312的第一端326及第二端328后，直接传送至第一切换开关310的第二端322及第一端320，亦即功率放大器302所输出的信号可直接传送至传输天线300，以通过无线电方式发射信号。换句话说，当发生紧急状况欲加强信号传输功能时，控制电路314可将功率放大器302所输出的信号不经过滤波器308的处理，而直接传送至传输天线300发射至空中。因此，当使用者遭遇紧急状况(如发生山难)时，本发明无线电信号传输装置30可加强移动通信装置的信号传输能力。On the other hand, when the user encounters an emergency (such as a mountain disaster) and wants to enhance the signal transmission function, the control circuit 314 switches the first end 320 of the first switch 310 through the control signals V2_SW1 and V2_SW2 to electrically connect to the second terminal 322 of the first switch 310 , and switch and electrically connect the first terminal 326 of the second switch 312 to the second terminal 328 of the second switch 312 . In this way, the signal output by the power amplifier 302 is directly transmitted to the second end 322 and the first end 320 of the first switch 310 after passing through the first end 326 and the second end 328 of the second switch 312, that is, The signal output by the power amplifier 302 can be directly transmitted to the transmitting antenna 300 for radio transmission. In other words, when an emergency occurs and the signal transmission function needs to be strengthened, the control circuit 314 can directly transmit the signal output from the power amplifier 302 to the transmission antenna 300 for transmission into the air without being processed by the filter 308 . Therefore, when the user encounters an emergency (such as a mountain disaster), the radio signal transmission device 30 of the present invention can enhance the signal transmission capability of the mobile communication device.

The radio signal transceiving device 40 is a radio signal transceiving device that enhances the signal transceiving function of a mobile communication device, and the mobile communication device may be an electronic device such as a mobile phone or a personal digital assistant. The radio signal transceiving device 40 comprises an antenna 400, a signal processing circuit 402, a down-frequency circuit 404, a low-noise amplifier 406, a frequency-up circuit 408, a power amplifier 410, a first filter 412, a second filter device 414 , a first switch 416 , a second switch 418 , a third switch 420 , a fourth switch 422 and a control circuit 424 . In addition, the radio signal transceiving device 40 may preferably include a third filter 426 interposed between the first filter 412 and the third switch 420, which functions as a surface acoustic wave filter. In the radio signal transceiver 40, the low noise amplifier 406 includes a first end 428 and a second end 430, the power amplifier includes a first end 432 and a second end 434, and the first switch 416 includes a first end 436 , a second end 438 and a third end 440, the second switch 418 includes a first end 442, a second end 444, a third end 446 and a fourth end 448, the third switch 420 includes a The first terminal 450 , a second terminal 452 and a third terminal 454 , the fourth switch 422 includes a first terminal 456 , a second terminal 458 and a third terminal 460 . The operation mode of the frequency reduction circuit 404 and the low noise amplifier 406 is similar to that of the frequency reduction circuit 204 and the low noise amplifier 202 of FIG. similar and will not be repeated here. In addition, the first switch 416 can switch the electrical connection to the second terminal 438 or the third terminal 440 according to a control signal V3_SW1 output by the control circuit 424, and the second switch 418 can switch the electrical connection according to a control signal V3_SW2 output by the control circuit 424. Connected to the second end 444, the third end 446, or the fourth end 448, the third switching switch 420 can be switched and electrically connected to the second end 452 or the third end 454 according to a control signal V3_SW3 output by the control circuit 424, and the fourth end The switching switch 422 can be switched to be electrically connected to the second terminal 458 or the third terminal 460 according to a control signal V3_SW4 output by the control circuit 424 . In the radio signal transceiving device 40 , the first filter 412 , the second filter 414 and the third filter 426 can filter the noise, so the signal strength can be reduced to a certain extent. In the present invention, the control circuit 424 can be used to transmit the signal received by the antenna 400 directly to the low-noise amplifier 406 without going through the first filter 412 and the third filter 426, or to transmit the power The signal output from the amplifier 410 is directly output from the antenna 400 without being filtered by the second filter 414 to enhance the received and transmitted signal strength. For the detailed operation of the radio signal transceiving device 40, please refer to the following description.

在一般接收情形下，控制电路424通过控制信号V3_SW1、V3_SW2及V3_SW3，将第一切换开关416的第一端436切换电连接到第一切换开关416的第二端438，将第二切换开关418的第一端442切换电连接到第二切换开关418的第三端446，以及将第三切换开关420的第一端450切换电连接到第三切换开关420的第三端454。如此一来，天线400所接收的信号经过第二切换开关418的第一端442与第三端446，及第一切换开关436的第一端436与第二端438后，由第一滤波器412及第三滤波器426过滤掉不必要的噪声，再通过第三切换开关420的第三端454及第一端450，输出至低噪声放大器406的第一端428。低噪声放大器406可将第一端428所接收的信号适度放大后，由第二端430输出至降频电路404。降频电路404将所接收的信号的频率降至一预设范围后输出至信号处理电路402，以进行后续信号处理。In a general receiving situation, the control circuit 424 switches and electrically connects the first end 436 of the first switch 416 to the second end 438 of the first switch 416 through the control signals V3_SW1, V3_SW2 and V3_SW3, and connects the second end 418 of the second switch 418 The first terminal 442 of the switch is electrically connected to the third terminal 446 of the second switch 418 , and the first terminal 450 of the third switch 420 is switched and electrically connected to the third terminal 454 of the third switch 420 . In this way, after the signal received by the antenna 400 passes through the first terminal 442 and the third terminal 446 of the second switch 418, and the first terminal 436 and the second terminal 438 of the first switch 436, it is transmitted by the first filter 412 and the third filter 426 to filter unnecessary noise, and then output to the first terminal 428 of the low noise amplifier 406 through the third terminal 454 and the first terminal 450 of the third switch 420 . The low noise amplifier 406 can properly amplify the signal received by the first end 428 and then output it to the frequency reduction circuit 404 through the second end 430 . The down-frequency circuit 404 reduces the frequency of the received signal to a preset range and outputs it to the signal processing circuit 402 for subsequent signal processing.

同理，在一般传输情形下，控制电路424通过控制信号V3_SW1、V3_SW2及V3_SW4，将第一切换开关416的第一端436切换电连接到第一切换开关416的第三端440，将第二切换开关418的第一端442切换电连接到第二切换开关418的第三端446，以及将第四切换开关422的第一端456切换电连接到第四切换开关422的第三端460。如此一来，信号处理电路402将欲传的信号通过升频电路408将信号频率提升至射频，再通过功率放大器410将信号的功率放大。功率放大器410输出的信号通过第四切换开关422的第一端456及第三端460后，由第二滤波器414过滤掉不必要的噪声，再通过第一切换开关416的第三端440及第一端436，输出至天线400，从而通过无线电方式发射信号。Similarly, in general transmission situations, the control circuit 424 switches and electrically connects the first terminal 436 of the first switch 416 to the third terminal 440 of the first switch 416 through the control signals V3_SW1, V3_SW2 and V3_SW4, and connects the second The first terminal 442 of the switch 418 is switched electrically connected to the third terminal 446 of the second switch 418 , and the first terminal 456 of the fourth switch 422 is switched and electrically connected to the third terminal 460 of the fourth switch 422 . In this way, the signal processing circuit 402 increases the frequency of the signal to be transmitted to a radio frequency through the frequency up-converting circuit 408 , and then amplifies the power of the signal through the power amplifier 410 . After the signal output by the power amplifier 410 passes through the first terminal 456 and the third terminal 460 of the fourth switch 422, the unnecessary noise is filtered out by the second filter 414, and then passes through the third terminal 440 and the third terminal 440 of the first switch 416. The first end 436 is output to the antenna 400 so as to transmit signals by radio.

换句话说，在一般情形下，第二切换开关418的第一端442始终电连接到第三端446，则不论接收或传输的信号都会经过滤波器的处理，以滤掉不必要的噪声。相反地，当使用者遭遇紧急状况(如发生山难)，而欲加强信号接收及传输功能时，本发明无线电信号收发装置40可控制第二切换开关418、第三切换开关420及第四切换开关422，以避免信号经过滤波器导致强度衰减。In other words, under normal circumstances, the first terminal 442 of the second switch 418 is always electrically connected to the third terminal 446 , and the received or transmitted signal will be processed by a filter to filter out unnecessary noise. Conversely, when the user encounters an emergency (such as a mountain disaster) and wants to enhance signal receiving and transmission functions, the radio signal transceiver 40 of the present invention can control the second switch 418, the third switch 420 and the fourth switch. The switch 422 is used to avoid intensity attenuation caused by the signal passing through the filter.

当紧急状况下要加强信号接收能力时，控制电路424通过控制信号V3_SW2及V3_SW3，将第二切换开关418的第一端442电连接到其第二端444，并将第三切换开关420的第一端450电连接到其第二端452，则天线400所接收的信号不会经过第一滤波器412及第三滤波器426的处理，而直接传送至低噪声放大器406，以进行后续的处理，因此可减少信号的衰减，从而加强信号接收能力。When the signal receiving capability needs to be strengthened in an emergency, the control circuit 424 electrically connects the first end 442 of the second switch 418 to its second end 444 through the control signals V3_SW2 and V3_SW3, and connects the first end 444 of the third switch 420 to One end 450 is electrically connected to its second end 452, then the signal received by the antenna 400 will not be processed by the first filter 412 and the third filter 426, but will be directly transmitted to the low noise amplifier 406 for subsequent processing , so the attenuation of the signal can be reduced, thereby enhancing the signal receiving ability.

同理，当紧急状况下要加强信号传输能力时，控制电路424通过控制信号V3_SW2及V3_SW4，将第二切换开关418的第一端442电连接到其第四端448，并将第四切换开关422的第一端456电连接到其第二端458，则功率放大器410所输的信号不会经过第二滤波器414的处理，而直接传送至天线400，因此可减少信号的衰减，从而加强信号传输能力。Similarly, when the signal transmission capability needs to be strengthened in an emergency, the control circuit 424 electrically connects the first terminal 442 of the second switch 418 to its fourth terminal 448 through the control signals V3_SW2 and V3_SW4, and connects the fourth switch 418 to the fourth terminal 448. The first end 456 of 422 is electrically connected to its second end 458, then the signal output by the power amplifier 410 will not be processed by the second filter 414, but will be directly transmitted to the antenna 400, so the attenuation of the signal can be reduced, thereby strengthening signal transmission capability.

因此，当使用者处于紧急状况下要加强信号接收及传输能力时，本发明无线电信号收发装置40可不经过滤波器的处理而接收或传输信号，以加强信号接收及传输能力。当然，为了避免噪声干扰及符合法规，无线电信号收发装置40可设定为当使用者处于紧急状况下且接收信号不良时，才启动上述功能。举例来说，若使用者拨打112等紧急救难码时，且接收信号不良时，才启动上述功能。如此一来，可避免噪声干扰及符合法规。Therefore, when the user wants to enhance the signal receiving and transmitting capability in an emergency situation, the radio signal transceiving device 40 of the present invention can receive or transmit the signal without processing by the filter, so as to enhance the signal receiving and transmitting capability. Of course, in order to avoid noise interference and comply with regulations, the radio signal transceiver device 40 can be set to activate the above functions only when the user is in an emergency and the received signal is poor. For example, if the user dials an emergency code such as 112 and the reception signal is poor, the above function will be activated. In this way, noise interference can be avoided and regulations can be complied with.

The operations of the first switch 310 and the second switch 312 are similar, and will not be repeated here. In the case of generally receiving signal signals, the control circuit 526 electrically connects the first terminal 528 of the first switch 516 to the third terminal 532 through the control signals V4_SW1, V4_SW2 and V4_SW5, and connects the first terminal 518 of the second switch 518 to the third terminal 532. 534 is electrically connected to third terminal 538 and electrically connects first terminal 552 of fifth toggle switch 524 to second terminal 554 . In this way, the signal received by the antenna 500 will be filtered by the first filter 512 to filter out unnecessary noise. Similarly, in the case of general signal transmission, the control circuit 526 electrically connects the first terminal 540 of the third switch 520 to the third terminal 544 through the control signals V4_SW3, V4_SW4 and V4_SW5, and connects the first terminal 544 of the fourth switch 522 to the third terminal 544. Terminal 546 is electrically connected to third terminal 550 and electrically connects first terminal 552 of fifth toggle switch 524 to third terminal 556 . In this way, the signal output by the power amplifier 510 will be filtered by the second filter 514 to filter out unnecessary noise.

相反地，在紧急状况下要加强信号接收能力时，控制电路526通过控制信号V4_SW1、V4_SW2及V4_SW5，将第一切换开关516的第一端528电连接到第二端530，将第二切换开关518的第一端534电连接到第二端536，以及将第五切换开关524的第一端552电连接到第二端554。如此一来，天线500所接收的信号不会经过第一滤波器512的过滤，以避免信号衰减。同理，在紧急状况下要加强信号传输能力时，控制电路526通过控制信号V4_SW3、V4_SW4及V4_SW5，将第三切换开关520的第一端540电连接到第二端542，将第四切换开关522的第一端546电连接到第二端548，以及将第五切换开关524的第一端552电连接到第三端556。如此一来，功率放大器510所输出的信号不会经过第二滤波器514的过滤，因此可避免信号衰减。Conversely, when the signal receiving capability is to be enhanced in an emergency, the control circuit 526 electrically connects the first terminal 528 of the first switch 516 to the second terminal 530 through the control signals V4_SW1, V4_SW2 and V4_SW5, and connects the second switch 516 to the second terminal 530. First terminal 534 of switch 518 is electrically connected to second terminal 536 , and first terminal 552 of fifth toggle switch 524 is electrically connected to second terminal 554 . In this way, the signal received by the antenna 500 will not be filtered by the first filter 512 to avoid signal attenuation. Similarly, when the signal transmission capability needs to be strengthened in an emergency, the control circuit 526 electrically connects the first end 540 of the third switch 520 to the second end 542 through the control signals V4_SW3, V4_SW4, and V4_SW5, and connects the fourth switch 520 to the second end 542. First terminal 546 of switch 522 is electrically connected to second terminal 548 , and first terminal 552 of fifth toggle switch 524 is electrically connected to third terminal 556 . In this way, the signal output by the power amplifier 510 will not be filtered by the second filter 514, thus avoiding signal attenuation.

因此，当使用者处于紧急状况下要加强信号接收及传输能力时，本发明无线电信号收发装置50可不经过滤波器的处理而接收或传输信号，以加强信号接收及传输能力。当然，为了避免噪声干扰及符合法规，无线电信号收发装置50可设定为当使用者处于紧急状况下且接收信号不良时，才启动上述功能。举例来说，若使用者拨打112等紧急救难码时，且接收信号不良时，才启动上述功能。如此一来，可避免噪声干扰及符合法规。Therefore, when the user wants to enhance the signal receiving and transmitting capability in an emergency situation, the radio signal transceiving device 50 of the present invention can receive or transmit the signal without processing by the filter, so as to enhance the signal receiving and transmitting capability. Certainly, in order to avoid noise interference and comply with regulations, the radio signal transceiving device 50 can be set to activate the above functions only when the user is in an emergency and the received signal is poor. For example, if the user dials an emergency code such as 112 and the reception signal is poor, the above function will be activated. In this way, noise interference can be avoided and regulations can be complied with.

综上所述，于紧急状况下要加强信号接收及传输能力时，本发明通过转换切换开关的操作，使所接收及传输的信号不通过滤波器的处理，以增加信号的强度，从而增加紧急状况下信号接收及传输的能力。To sum up, when it is necessary to strengthen signal receiving and transmission capabilities in emergency situations, the present invention makes the received and transmitted signals not pass through the processing of the filter by switching the operation of the switch, so as to increase the strength of the signal, thereby increasing the emergency response. The ability to receive and transmit signals under certain conditions.
