abstract = {In this paper, class E inverting and synchronous rectifying functions, implemented over GaN HEMT dies, are properly integrated for the design of a 1 GHz polar transmitting architecture. Employing high-Q lumped-element passive networks, an implementation with a high power density also results. The amplitude and phase components of a 5 MHz multisine are shown to be properly recombined at the output of an 80% efficient RF power amplifier (RFPA), drain modulated by means of a resonant DC/DC converter with a peak efficiency of 77%. A frequency-modulation (FM) coding of the envelope is here proposed for the converter, resulting in a 20 MHz large-signal bandwidth and a 720 V/μSeg slew-rate value.},
