摘要

提出了一种高效率、高工作电压的GaAs HFET。提出了一种无射频反馈的平衡级联电路，该电路在2.1GHz时可达到78.2%的高PAE。对平衡电容器的优化进行了理论分析和实验验证。这一结果有助于用低击穿电压晶体管设计高压功率放大器。

A high efficiency, high voltage, balanced cascode FET

A high efficiency, high operating voltage GaAs HFET is presented. A balanced cascode circuit without RF feedback, which achieves the high PAE of 78.2% at 2.1GHz, is proposed. The optimization of a balance capacitor is analyzed theoretically and proved experimentally. This result contributes to the design of high voltage power amplifiers with low breakdown voltage transistors.
