Abstract
A power amplifier system for high efficiency signal amplification of digitally modulated carrier signal or multi-carrier signals is disclosed. The linearity of the amplifier is improved by providing dynamic load line adjustments through implementation of suitably defined transfer functions employing dynamic control of operational aspects of active devices in the power amplifier.
