Fig. 6 A is shown in some embodiments, and diversity receiver configuration 600 may include DRx module 610, DRx module 610 have one or more phase matched component 624a-624b.DRx module 610 includes being couple to antenna from DRx module 610 Two paths of 140 output for being couple to transmission line 135 for being input to DRx module 610.

In the DRx module 610 of Fig. 6 A, demultiplexer and bandpass filter are embodied as duplexer 611.Duplexer 611 Including being couple to the input of antenna 140, being couple to the first output of the first amplifier 314a and being couple to the second amplifier 314b Second output.At the first output, duplexer 611 export received at input (for example, from antenna 140), filtering to The signal of first frequency band.At the second output, duplexer 611 exports receive in input, filtering to second frequency band Signal.In some embodiments, duplexer 611 can use triplexer (triplexer), four work devices (quadplexer) or any other multiplexer replaces, which is will in the defeated of DRx module 610 Enter multiple signals along multiple propagateds that the input signal that place receives is separated at corresponding multiple frequency bands.

As described above, the one path setting of correspondence of each of the amplifier 314a-314b in each path, and match It is set to the signal that amplification receives at amplifier.The output of amplifier 314a-314b is combined it combining 612 by signal Before, it is fed past corresponding phase-shifting elements 624a-624b.

Signal combiner 612 includes the first input for being couple to the first phase-shifting elements 624a, is couple to the second phase-shifting elements The second of 624b inputs and is couple to the output of the output of DRx module 610.Signal at the output of signal combiner is first The sum of the signal of input and the second input.Therefore, signal combiner is configured to combine the signal along multiple propagateds.

When antenna 140 receives signal, which arrives first frequency band by the filtering of duplexer 611, and passes through first Amplifier 314a is propagated along first path.Filtering and amplified signal are presented by the first phase-shifting elements 624a progress phase shift It is sent to the first input of signal combiner 612.In some embodiments, signal combiner 612 or the second amplifier 314b be not Signal is prevented to continue through signal combiner 612 along the second path in the opposite direction.Therefore, signal propagates through the second phase shift Component 624b and by the second amplifier 314b, it is reflected off duplexer 611 there.Reflection signal propagates through second Amplifier 314b and the second phase-shifting elements 624b, with the second input of arriving signal combiner 612.

When (the first input of signal combiner 612) initial signal and (the second input of signal combiner 612 ) reflection signal out-phase (out-of-phase) when, the superposition (sumation) executed by signal combiner 612 leads to signal group Signal reduction at the output of clutch 612.Similarly, it when initial signal and reflection signal are with phase, is held by signal combiner 612 Capable superposition leads to the signal enhancing at the output of signal combiner 612.Therefore, in some embodiments, the second phase shift portion Part 624b is configured to carry out phase shift to (at least in first frequency band) signal, so that initial signal and reflection signal at least portion Divide same phase.Particularly, the second phase-shifting elements 624b is configured to carry out phase shift to (at least in first frequency band) signal, makes The amplitude for obtaining the sum of initial signal and reflection signal is greater than the amplitude of initial signal.

For example, the second phase-shifting elements 624b can be configured to passing through the signal of the second phase-shifting elements 624b by by passing through The backpropagation of second amplifier 314b is reflected off duplexer 611 and is drawn by the forward-propagating of the second amplifier 314b - 1/2 times of progress phase shift of the phase shift entered.As another example, the second phase-shifting elements 624b can be configured to passing through second The signal of phase-shifting elements 624b by 360 degree with by by the backpropagation of the second amplifier 314b, be reflected off duplexer 611, And phase shift is carried out by the half of the difference between the introduced phase shift of the forward-propagating of the second amplifier 314b.Generally, second Phase-shifting elements 624b can be configured to carry out phase shift to the signal for passing through the second phase-shifting elements 624b, so that initial signal and anti- Penetrate phase difference of the signal with 360 degree of integral multiple (including zero).

As an example, initial signal can pass through the anti-of the second amplifier 314b 0 degree (or any other reference phase) To the phase shift for propagating, being reflected off duplexer 611 and 140 degree being introduced by the forward-propagating of the second amplifier 314b.Cause This, in some embodiments, the second phase-shifting elements 624b be configured to pass through the signal of the second phase-shifting elements 624b by- 70 degree of progress phase shifts.Therefore, initial signal moves on to -70 degree by the second phase-shifting elements 624b phase, is passed through the second amplifier 314b Backpropagation, be reflected off duplexer 611 and the forward-propagating by the second amplifier 314b and mutually move on to 70 degree, and by Second phase-shifting elements 624b phase is moved back into 0 degree.

In some embodiments, the second phase-shifting elements 624b is configured to the letter for passing through the second phase-shifting elements 624b Number press 110 degree of progress phase shifts.Therefore, initial signal moves on to 110 degree by the second phase-shifting elements 624b phase, is passed through the second amplifier The backpropagation of 314b is reflected off duplexer 611 and the forward-propagating by the second amplifier 314b and mutually moves on to 250 degree, and And 360 degree are moved on to by the second phase-shifting elements 624b phase.

Meanwhile signal received by antenna 140 arrives second frequency band by the filtering of duplexer 611, and puts by second Big device 314b is along the second propagated.Filtering and amplified signal are fed by the second phase-shifting elements 624b progress phase shift To the second input of signal combiner 612.In some embodiments, signal combiner 612 or the first amplifier 314a do not hinder Stop signal continues through signal combiner 612 along first path in the opposite direction.Therefore, signal propagates through the first phase shift portion Part 624a and by the first amplifier 314a, it is reflected off duplexer 611 there.Reflection signal propagates through first and puts Big device 314a and the first phase-shifting elements 624a, with the first input of arriving signal combiner 612.

When (the second input of signal combiner 612) initial signal and (the first input of signal combiner 612 ) reflection signal out-phase when, cause the signal of the output of signal combiner 612 weak by the superposition that signal combiner 612 executes Change, when initial signal is with signal is reflected with phase, the defeated of signal combiner 612 is led to by the superposition that signal combiner 612 executes The signal enhancing in source.Therefore, in some embodiments, the first phase-shifting elements 624a is configured to (at least in second frequency In band) signal carries out phase shift, so that initial signal and reflection signal at least partly same phase.

For example, the first phase-shifting elements 624a can be configured to passing through the signal of the first phase-shifting elements 624a by by passing through The backpropagation of first amplifier 314a is reflected off duplexer 611 and is drawn by the forward-propagating of the first amplifier 314a - 1/2 times of progress phase shift of the phase shift entered.As another example, the first phase-shifting elements 624a can be configured to passing through first The signal of phase-shifting elements 624a by 360 degree with by by the backpropagation of the first amplifier 314a, be reflected off duplexer 611, And phase shift is carried out by the half of the difference between the introduced phase shift of the forward-propagating of the first amplifier 314a.Generally, first Phase-shifting elements 624a can be configured to carry out phase shift to the signal for passing through the first phase-shifting elements 624a, so that initial signal and anti- Penetrate phase difference of the signal with 360 degree of integral multiple (including zero).

Phase-shifting elements 624a-624b implementable is passive circuit.Particularly, it is LC that phase-shifting elements 624a-624b is implementable Circuit, and one or more passive components including such as inductor and/or capacitor etc.Passive component can be in parallel And/or be connected in series, and can connect between the output of amplifier 314a-314b and the input of signal combiner 612, Or it can connect between the output and ground voltage of amplifier 314a-314b.In some embodiments, phase-shifting elements 624a- 624b is integrated into chip (die) identical with amplifier 314a-314b or is integrated into same package.

In (for example, as shown in Figure 6A) some embodiments, phase-shifting elements 624a-624b exists along path setting After amplifier 314a-314b.Therefore, any signal decaying as caused by phase-shifting elements 624a-624b does not influence module 610 Performance, such as the signal-to-noise ratio of output signal.However, in some embodiments, phase-shifting elements 624a-624b is set along the path It sets before amplifier 314a-314b.For example, phase-shifting elements 624a-624b can be integrated into duplexer 611 and amplifier In the impedance match part being arranged between 314a-314b.

In some embodiments, DRx controller 702 is tuned tunable phase shift component 724a-724d based on band selected signal. For example, DRx controller 702 can be tuned tunable phase shift component 724a-724d based on look-up table, which will be by frequency Frequency band (or frequency band group) with selection signal instruction is associated with tuner parameters.Accordingly, in response to band selected signal, DRx controller 702 can send phase shift tuning signal to the tunable phase shift component 724a-724d of each activated path, with basis Tuner parameters are tuned tunable phase shift component (or its units of variance).

DRx controller 702 can be configured to be tuned tunable phase shift component 724a-724d, so that with external reflectance signal At output multiplexer 312 and with the same phase of outer initial signal.For example, if band selected signal instruction is corresponding with first frequency band (passing through the first amplifier 314a's) first path, (by second amplifier 314b) second corresponding with second frequency band Path and (passing through third amplifier 314c's) third path will be activated, then DRx controller 702 can be to the first tunable phase shift Component 724a is tuned, so that (1) is for (at second frequency band) along the signal of the second propagated, initial signal and edge First path backpropagation is reflected off bandpass filter 313a and same by the reflection signal of first path forward-propagating Phase, and (2) are directed to (at third frequency band) along the signal of third propagated, and initial signal is reversely passed with along first path It broadcasts, be reflected off bandpass filter 313a and pass through the same phase of reflection signal of first path forward-propagating.

DRx controller 702 can be tuned the first tunable phase shift component 724a, so that the phase-shift phase of second frequency band is not It is same as third frequency band.For example, if due to by the backpropagation of the first amplifier 314a, being reflected off bandpass filter 313a and forward-propagating by the first amplifier 314a, the signal at second frequency band have been phase-shifted 140 degree and third frequency Signal at rate band has been phase-shifted 130 degree, then DRx controller 702 can be tuned the first tunable phase shift component 724a, will Second frequency band phase shift -70 spends (or 110 degree) and (or 115 degree) is spent in third frequency band phase shift -65.

DRx controller 702 can similarly carry out the second tunable phase shift component 724b and third tunable phase shift component 724c Tuning.

The units of variance of tunable phase shift component 724a-724d can be tuned as having by DRx controller 702 is used for different frequency Different value with group.

In some embodiments, tunable phase shift component 724a-724d is untunable using DRx controller 702 or controls Fixed phase drift component replace.Each phase shift of corresponding path setting corresponding with a frequency band in multiple paths Each phase-shifting elements in component can be configured to each carry out phase shift in other frequency bands, so that along corresponding other paths Initial signal with along the backpropagation of one of the path, be reflected off corresponding bandpass filter and by the path it The same phase of reflection signal of one forward-propagating.

For example, third phase-shifting elements 724c, which can be fixed and be configured as (1), carries out phase shift to first frequency band, So that the initial signal of (propagating along first path) first frequency band is reflected off third band with along the backpropagation of third path Bandpass filter 313c and the same phase of reflection signal for passing through the forward-propagating of third path, (2) carry out phase shift to second frequency band, make It obtains the initial signal of second frequency band (along the second propagated) and is reflected off third band logical with along the backpropagation of third path Filter 313c and phase shift is carried out to the 4th frequency band by the same phase of reflection signal of third path forward-propagating, and (3), So that the initial signal of (along the 4th propagated) the 4th frequency band is reflected off third band with along the backpropagation of third path Bandpass filter 313c and the same phase of reflection signal for passing through the forward-propagating of third path.Other phase-shifting elements can be similarly solid It is fixed and configured.

Therefore, DRx module 710 includes DRx controller 702, be configured to selectively to activate the input of DRx module 710 with One or more of multiple paths between the output of DRx module 710.DRx module 710 further includes multiple amplifier 314a- One path of correspondence of each amplifier in multiple paths in 314d, multiple amplifier 314a-314d is arranged and configures To be amplified to the signal received at amplifier.DRx module further includes multiple phase-shifting elements 724a-724d, Duo Gexiang One path of correspondence of each phase-shifting elements moved in component 724a-724d in multiple paths is arranged and configured to transmitting Phase shift is carried out by the signal of phase-shifting elements.

Fig. 8 is shown in some embodiments, and diversity receiver configuration 800 may include DRx module 810, DRx module 810 have one or more impedance match part 834a-834b.DRx module 810 includes being couple to antenna from DRx module 810 Two paths of 140 output for being couple to transmission line 135 for being input to Rx module 810.

In the DRx module 810 of Fig. 8 (as in the DRx module 610 of Fig. 6 A), demultiplexer and bandpass filtering Device is embodied as duplexer 611.Duplexer 611 includes the input for being couple to antenna, is couple to the first impedance match part 834a's First output and the second output for being couple to the second impedance match part 834b.At the first output, the output of duplexer 611 exists Signal that input (for example, from antenna 140) receives, filtering to first frequency band.At the second output, duplexer 611 The signal of second frequency band is arrived in output is received in input, filtering.

Each impedance match part 834a-834b is arranged between duplexer 611 and amplifier 314a-314b.Institute as above It states, the one path setting of correspondence of each of the amplifier 314a-314b in each path, and is configured to amplification and is amplifying The signal received at device.The output of amplifier 314a-314b is fed to signal combiner 612.
