摘要

采用0.15 μm砷化镓(GaAs)技术，设计了一种谐波调谐输出匹配网络的叠置场效应管功率放大器。该放大器的输出功率为28.5 dBm，增益为12 dB，功率附加效率(PAE)为38.4%。据我们所知，这是第一次将堆叠fet技术与谐波调谐输出网络相结合，在GaAs PA中同时实现高PAE和高功率密度。

A High Efficiency High Power Density Harmonic-Tuned Ka Band Stacked-FET GaAs Power Amplifier

A stacked-FET power amplifier (PA) with harmonic- tuned output matching network is demonstrated using a 0.15-μm Gallium Arsenide (GaAs) technology. The fabricated PA exhibits 28.5 dBm output power, 12 dB gain and 38.4% power added efficiency (PAE). To the best of our knowledge, this is for the first time stacked-FET technique is used in combining with harmonic-tuned output network to achieve high PAE and high power density simultaneously in a GaAs PA.
