EXACT DESIGN OF A WIDE-BAND WAVEGUIDE DUPLEXING FILTER
频率和极化复用的群分波器的准确设计

After solving the boundary value problem of a waveguide junction, the exact design method of a wide-band duplexing filter for 4 and 6 GHz relay communication is obtained by using the concept of equivalent circuit. The theoretical results are in good agreement with the measured data. This design method can be used for other wide-band duplexer with similar construction.
