Abstract
A transmitter which comprises a rf carrier signal generator for generating a rf carrier, a Class C amplifier arranged to amplify the rf carrier, a power supply for the Class C amplifier, a detector for detecting the modulated rf carrier and establishing a detected signal, a controller for controlling the power supply, means for supplying an audio signal to the controller for the purpose of amplitude modulating the rf carrier, and wherein the audio signal and the detected signal are applied to the controller to compensate for the non-linearily of the Class C amplifier.
