Abstract
In this contribution, the design of an uneven AB-C Doherty power amplifier (DPA) in GaN technology, implementing a new approach to control the higher device harmonics, is presented. The DPA was designed to operate at 2.14 GHz and with the aim to reduce as much as possible the chip size, without losing the Doherty operating principle. The measurement results in CW conditions at 2.14 GHz had shown average drain efficiency higher than 55% at 6 dB of back-off, with a saturated output power of 37 dBm.
