摘要： A method and system of frequency for multiplying a signal (data in) having amplitude modulated by an amplitude modulator (10) using a frequency multiplier (13) operated at a bias voltage that is less than its saturation mode voltage. Prior to amplification, the amplitude modulated signal is pre-distorted by a pre-distorting stage (14, 15) to compensate for distortion caused by the frequency multiplier (13). The pre-distorting stage comprises a first pre-distortion phase (14) for converting the amplitude modulated signal into a corresponding square root signal to compensate for a first distortion type and a second pre-distortion phase (15) for pre-distorting the square root signal to compensate for the distortion caused by biasing the frequency multiplier (13) at a voltage less than the saturation voltage of the multiplier. As a result, a signal that is amplitude-modulated can be multiplied by a frequency multiplier (13).
