摘　　要：设计了一种具有高功率容量的高功率微波(high power microwave,HPM)耦合测量装置。该装置使用截止波导对HPM信号取样,并经过同轴探针将取样信号耦合到同轴电缆中。截止波导可以限制进入耦合单元的射频功率,同时,截止波导和传输高功率微波的主波导连接处允许大的倒角,因此,该耦合装置能够保证较高的功率容量。此外,通过调节截止波导中探针的长度,可以实现不同的耦合度,容易满足不同功率水平HPM测量的应用需求。与传统的耦合器相比,所设计的耦合器结构简单且功率容量高,其可行性已经得到了HPM实验的证实。A high power capacity coupler was designed for high power microwave（HPM）measurement.The coupler uses a cut-off waveguide to receive HPM signals and couples them into the coaxial cables through the coaxial probe.The cut-off waveguide can effectively limit the RF power coupled by the coupler and allow a large corner radius in the joint of the main waveguide and the cut-off waveguide.The variable probe is fixed in the cut-off waveguide so that the coupling degree can be easily adjusted.Compared with the conventional couplers,the proposed coupler has a simpler structure and a higher power capacity.The proposed coupler has been fabricated and demonstrated by an X-band HPM experiment.
