Abstract
A system improve amplifier efficiency of operation relative to that of an amplifier with fixed biasing and fixed matching conditions receives a power level and an indicator of amplifier operation. The indicator is at least one of channel, channel bandwidth, out-of band spectral requirements, spectral mask requirements, error vector magnitude, modulation rate, and modulation type. A controller generates a control signal based at least in part on the power level and the indicator to control at least one of the bias current and the matching conditions of matching circuits. The matching conditions and bias current for channels at an edge of a channel band are different from the bias current and matching conditions for channels nearer a center of the channel band.
