摘　　要：双工器是通信系统中重要的选频滤波器件,该文设计研制了一款Ka波段波导双工器。该双工器是由一个H面T型结构和两个E面波导滤波器组成,通带为29 29.5GHz和30.5 31GHz,带内插损为1.5dB以内,带间隔离度为80dB以上,具有良好的滤波选频功能。Abstraet：Duplexer plays an important part in the communication system. This paper shows a Ka - band waveguide duplexer. It is combined by an H-plane T-junction and two E-plane waveguide filters. The pass band of the duplexer is 29 -29.5GHz and 30.5 -31GHz. The duplexer has good performance that the insert loss of the pass band is less than 1.5 dB while the isolation between the two pass bands is more than 80dB.
