Apparatus and method are presented for compensating for carrier signal phase distortion caused by amplitude modulating an RF cannier signal. A modulator- amplifier network receives an RF carrier signal and modulates it by a received amplitude varying signal to obtain therefrom a modulated RF carrier signal which is phase shifted from the phase of the carrier signal applied to the network by an amount that varies with the value of the amplitude varying signal. A phase shifter receives the RF carrier signal and phase shifts it in accordance with the value of a received phase correction signal to provide a pre-phase shifted carrier signal that is applied to the modulator-amplifier network. A phase detector receives and compares the modulated RF carrier signal and the carrier signal and provides an error signal in accordance with the comparison. A controller provides the correction signal and receives the error signal and the amplitude varying signal and varies the value of the correction signal in accordance with the value of the error signal and the value of the amplitude varying signal.
