ABSTRACT:
A power controller for a class C radio frequency power amplifier that exhibits an output power threshold, including a detector circuit (299) that detects a output power level to provide a level signal when the radio frequency power amplifier has achieved the output power threshold, and a comparator apparatus (245) that combines a reference signal and the level signal to provide a control signal that is arranged to establish the output power level, and a generator function (247) that provides the comparator apparatus a substitute level signal until the amplifier has achieved the output power threshold.
