✦ Synopsis

Abstract

A Doherty amplifier's theoretical gain and efficiency characteristics significantly exceed those achieved by practical simulations and implementations. Analysis and simulation demonstrates that the FET gate voltage to drain current transfer characteristic has a significant detrimental effect on these characteristics, indicating it is the major factor in the difference between ideal and practical results.

## Abstract In this article, we propose the optimum design of a highly linear and efficient Doherty power amplifier (DPA) considering the soft turn‐on effects of the GaN HEMT. To compensate for the soft turn‐on characteristic and obtain an extended high‐efficiency range, the DPA is designed with un
