Abstract

Embodiments of methods, transceiver circuits, and systems can compensate an IQ mismatch (e.g., Tx or Rx) or a carrier leakage using a plurality of local oscillators. One embodiment of a transceiver can include a first up-conversion IQ mixer, a second up-conversion IQ mixer, a first down-conversion IQ mixer with an input to receive an output of the second up-conversion IQ mixer, a second down- conversion IQ mixer with an input to receive an output of the first up-conversion IQ mixer, a first local oscillator to generate a first IQ LO signal for the first up- conversion IQ mixer and the first down-conversion IQ mixer, and a second local oscillator to generate a second IQ LO signal for the second up-conversion IQ mixer and the second down-conversion IQ mixer.
