abstract = {In this paper, a class E³ polar transmitter is
 presented, aimed to handle envelope-varying communication
 signals with high power efficiency. Implemented at UHF band,
 it combines a class E RF PA, excited by a phase modulated
 constant envelope signal, with a class E² DC/DC converter,
 aimed to high-level and synchronously modulate the RF PA
 according to the amplitude component. Using GaN HEMT
 technology, both for the RF and the envelope power stages, and
 after applying digital predistortion (DPD), a global average
 efficiency over 40% is obtained for an EDGE signal.},
