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 8~18 GHz和34~36 GHz,带内插损在8~18 GHz小于1 dB, 34~36 GHz小于1.8 dB,隔离度在34~36 GHz大于30 dB,在8~18 GHz大于10 dB,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 GHz 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 be-tween the two pass bands of the devices,the diplexer can satisfy the requirement of the application.
