ABSTRACT:
An FET linear power amplifying apparatus with an FET power amplifier and a distortion generator which produces a distortion signal indicative of a distortion component having the same amplitude and inverted phase as those of a distortion component produced by the FET power amplifier. The amplitude and the phase of the distortion signal are controlled in accordance with a control signal which depends upon the magnitude ratio of the input and output signals of the apparatus. The distortion component which will be produced by the FET power amplifier is compensated by the controlled distortion signal.
