✦ Synopsis

Abstract

A Doherty amplifier is described in which odd harmonics from the class‐C peaking amplifier flow to the main amplifier to achieve class‐F operation, without the need for complicated space consuming harmonic control circuits. The measured efficiency exceeded 50% above the 6 dB back‐off. The measured second and third harmonic levels were below −19 dBc. © 2011 Wiley Periodicals, Inc.

## Abstract In this article, we report the linearity improvement of the GaN HEMT class‐E Doherty power amplifier (CEDA). For the linearity improvement, not only the gate biases but also the matching circuits of the carrier and peaking cells are optimally controlled at a pout of 38 dBm, which is a 7
