在F类功率放大器的基本工作原理和设计方法的基础上，采用开路枝节微带线匹配的方法实现了F类功率放大器所需要的谐波阻抗匹配，并采用GaN HEMT晶体管设计制作了应用于无线通讯领域的双级高效高增益F类功率放大器。在2.65 GHz工作频率，该功率放大器具有65.69%功率附加效率（PAE）、20 dB的功率增益和10 W输出功率。该功率放大器的实测结果与电路仿真结果相吻合，证明了使用该方法设计F类功率放大器的有效性。

In this paper, we use an open stub microstrip line to realize harmonic impedance matching of a class-F PA. We analyze the fundamental design methods of a class-F PA and design a two-stage high-efficiency, high-gain class-F PA using GaN HEMT. At 2.65 GHz, the PA has 65.69% power-added efficiency, 20 dB gain, and 10 W output. The measured results conform with the circuit simulations, and this proves that our design method is effective.
