Abstract

A circuit-simulation-based optimization technique is utilized to automatically design a HEMT-based Doherty power amplifier (PA) at 3.5 GHz. The newly proposed approach integrates a multi-objective evolutionary algorithm and ADS® circuit simulator running on the platform of the unified optimization framework. In terms of several key factors of the explored PA including layout constraints, we can optimize the power-Added efficiency, the output power, and the gain simultaneously, where the remarkable 51.3%, 43.7 dBm, and 7.5 dB, have been achieved correspondingly.
