Abstract
The present invention relates to methods and devices to control and operate the functionality of a power amplifier system () capable of operating in at least three differential amplification modes. The drive signal's amplitude envelope controls an integrated switch network () that routes both the signal envelope and signal phase to different modulation blocks (). Depending on the envelope strength, the operational mode of the amplifier system is possible to alter to best serve the signal statistics to provide the highest overall power efficiency.
