Abstract
A method is disclosed wherein a power level indicating a level of transmission power from an amplifier is provided. An indication of at least one of channel, channel bandwidth, OOB spectral requirements, spectral mask requirements, EVM, modulation rate, and modulation type is also provided. A control signal for controlling one of a bias current provided to the amplifier and a matching circuit for matching an output port of at least a stage of the amplifier is generated, the control signal determined in dependence upon the power level and the at least an indication. Then the one of the bias current and the matching circuit is adjusted in accordance with the control signal.
