## Abstract In this article, we propose a highly linear and efficient three‐way Doherty amplifier using two‐stage GaN HEMT cells for repeater systems. The driving cells are used as the predistortion circuit to improve linearity as well as the gain stage. The main cells are optimized to achieve high

## Abstract A balanced class‐E power amplifier (PA) using a push‐pull GaN HEMT for high power and high efficiency is represented. For validation, a class‐E PA is designed and implemented using a push‐pull type GaN HEMT and tested for a single tone of 2.14 GHz. The measured results show that the bal
