## Abstract Load impedance modulation and gate bias control were investigated to improve the performance of W‐CDMA base‐station envelope tracking amplifiers by means of simulations based on the measured data of a 10‐W GaAs FET power amplifier. It is shown that adapting the load impedance along with
