Abstract

See full text

A method for power amplification uses circuitry including a main amplifier and an auxiliary amplifier that are constructed and operate such that an input is applied to the main and auxiliary amplifiers via an input network. At low power levels, the auxiliary amplifier is off and the main amplifier sees a large impedance. At maximum power level, both the auxiliary and main amplifiers operate at full power and there is a constant phase shift between them. While transitioning from low to maximum power, systematic AM-AM and AM-PM variations generated due to the phase shift provided by the input network, bias differences between the main and auxiliary amplifiers, and nature of the output combiner to compensate device related distortions.
