摘要
平行板径向波导功率合成器具有工作频带宽，低插入损耗，与放大器和传输线匹配良好，端口隔离度较高，功率容量大等特点。设计了一个1.5 kW宽带6路径向波导功率合成器，CST软件仿真结果表明：该合成器在驻波比小于1.1的情况下，其工作频带为1.35-3.3 GHz，合成效率达到96%。
Parallel-plate radial-waveguide combiner has the properties of broad bandwidth,low insertion loss,good matching to amplifiers and transmission lines,good isolation between the ports and high power capacity.In this paper,a 6-ways broadband radial-waveguide combiner with output power of 1.5 kW is presented.The CST simulation results show that this combiner achieves broad operating band,which cover 1.35-3.3 G,with a SWR less than 1.1.Across the passband,a high combine efficiency reaches 96%,and the isolation greater than 7 dB.
