摘要：
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.
