Abstract
In this paper, a novel supply modulator for envelope tracking power amplifier was presented, which boosts operation bandwidth capability to tracking up to LTE 60MHz by utilizing GaN MOSFET and compatible with feed forward loop to linearize the modulator for wideband, realizing high efficiency trading off linearity as well.
