Abstract
A system and method improve amplifier efficiency of operation relative to that of a matching circuit with fixed matching conditions. A power level representing a level of transmission power from an amplifier circuit and an indicator of amplifier circuit operation are provided. 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. The matching conditions for a matching circuit of an amplifying transistor are adjusted based at least in part on the power level and the indication where the matching conditions are different for channels at an edge of a channel band than for channels nearer a center of the channel band.
