摘　　要：随着小型化的需求,腔体双模滤波器因体积小、重量轻等优点被越来越广泛的应用于通信系统中.本文在分析腔体模式的基础上,利用腔体一边切角的方法实现腔体中简并模式之间的耦合,设计出了单腔体双模滤波器,并得出了影响腔体双模滤波器滤波特性的关键尺寸。To meet the requirements of miniaturization,dual mode cavity filters are more widely used in communication systems due to their compact size and light weight.Based on analysis of cavity mode,coupling between degenerate modes was realized by cutting an angle on one edge of the cavity,dual mode single cavity filters were designed and the key dimensions affecting the filtering characteristics of the filters were determined.
