谐振环可以通过波的耦合来放大RF功率，用于高功率击穿测试、单向滤波器或脉冲整形技术。通常，谐振环的RF输出端子连接到匹配负载。对于北京大学的谐振环，匹配负载已被替换为波导短路板，以获得更高的调节功率为1.3 GHz的电容型功率耦合器。在相同的输入RF功率下，通过这种短端接，功率增益显著增加。本文将介绍这种改进型谐振环的工作机理分析、实验和结果。
Resonant rings which can amplify RF power through the coupling of waves are used for high power breakdown tests, unidirectional filters, or pulse-shaping techniques. Usually, the RF output terminal of a resonant ring is connected to a matched load. For the resonant ring at Peking University, the matched load has been replaced by a waveguide shorting plate to obtain higher conditioning power for the 1.3 GHz capacitive type power couplers. The power gain is increased significantly with this short termination with the same input RF power. Working mechanism analysis, experiments, and results of this modified resonant ring will be presented.
