Abstract
A system for compensating gain control variations in a power amplifier comprises a power control element configured to receive a power control signal and an instantaneous envelope power reference signal, an adder configured to combine the power control signal and the instantaneous envelope power reference signal to obtain a modified power level signal, and a mapping function configured to receive the modified power level signal and configured to alter a control input to a variable gain amplifier, the variable gain amplifier controlling an adjustable input to the power amplifier.
