## Abstract A highly efficient and linear inverted Doherty power amplifier (IDPA) with unsymmetrical delay path is presented. To compensate the phase difference between carrier and peaking cells, an additional offset line is inserted at the input path of the carrier cell. For verification, the IDPA

## 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 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
