摘要: 在数值分析的基础上，采用加宽的波导结构设计了一种S波段三路高功率微波输出多工器，通带范围分别为2.65~2.75，2.80~2.90和2.95~3.05 GHz。该多工器每路的传输损耗在0.1 dB以下，反射损耗在15 dB以上，各路之间的隔离度在30 dB以上，能量效率在95%以上。利用电磁场全波分析软件，验证了宽边加宽的波导输出多工器功率容量达到GW量级。Abstract: An S band high power microwave multiplexer with three channels is investigated through numerical computation. The realized multiplexer works in the band of 2.65~2.75, 2.80~2.90 and 2.95~3.05 GHz. In each pass band, the transmission loss is less than 0.1 dB and the reflection loss is more than 15 dB, the isolation is more than 30 dB. As a result, the energy efficiency is as high as 95%. The power handling capacity of the multiplexer with widened waveguide is demonstrated to be GW level by a full wave analysis software.
