摘　　要：介绍了一种宽频带毫米波微带双工器，该双工器通过一个低通滤波器和一个高通滤波器并联构成，具有工作频率高、工作频带宽、体积小、插损低等特点，通带频率为8～18GHz和34～36GHz，带内插损在8～18GHz小于1dB，34～36GHz小于1．8dB，隔离度在34～36GHz大于30dB，在8～18GHz大于10dB，由于双工器两频带相距较远，应用时两频段之间器件隔离较好，因此低的隔离度不影响双工器的实际应用。A kind of wideband millimeter wave microstrip diplexer is introduced, which is made up of parallel connection of a low pass filter and a high pass filter, and has high working frequency, broad working band, low insertion loss and small volume. The pass band of the diplexer is 8 - 18 GHz and 34 - 36 GHz. Its insertion loss is less than 1 dB in 8 -18 GI-Iz and 1.8 dB in 34 - 36 GHz. Its isolation is just more than 30 dB in 34- 36 GHz and 10 dB in 8 -18 GHz. Because of the high isolation between the two pass bands of the devices, the diplexer can satisfy the requirement of the application.
