Abstract
Power amplifiers are important blocks in communication systems and their efficiency and linearity are critical performance parameters. In this paper, we present a preliminary investigation into RF feedback systems designed to improve the efficiency-linearity trade-off for power amplifiers. We demonstrate very large potential improvement in trade-off due to feedback and significant actual improvement. In order to fully realise the potential improvement, further work needed is outlined.
