An RF amplifier for a phase and envelope varying signal employs a class C operated device for high efficiency. In order to improve the linearity of the class C operated device, a signal corresponding to the envelope of the amplifieroutput is formed and a portion thereof is fed back to an envelope modulation element such as a pulse width modulator connected to the class C operated device to reduce distortion at the amplifier output.
