A full-duplex radio transceiver includes a transmitter and a receiver. A duplexer is connected to an output of the transmitter and an input of the receiver. The receiver includes a low noise amplifier having a nonlinear portion capable of generating undesired cross-modulation signals based upon a portion of the transmit signal coupled thereto from the duplexer and a signal from another adjacent transmitter. A bandpass filter is connected to an output of the low noise amplifier, and at least one downconverter stage is connected to an output of the bandpass filter. A reactive termination circuit is connected between the low noise amplifier and the bandpass filter for changing an impedance presented to the output of the low noise amplifier with respect to signals from the colocated transmitter to thereby reduce undesired cross-modulation signals.
