摘　　要：微带带通滤波器在射频系统中应用非常广泛,随着卫星通信技术的发展,对频段、带宽的要求越来越高,宽带微带带通滤波器的设计也益发的重要。文中分析了等宽耦合线节级联设计法设计平行耦合线带通滤波器的基本原理,应用自编设计程序设计并实现了一个相对带宽为33%的S波段平行耦合线带通滤波器,在电路结构的处理上考虑了小型化,测试结果表明性能满足指标要求。The applications of the microstrip bandpass filter in RF systems is very wide. With the development of satellite communications technique, its demand on frequency and bandwidth is more and more strict and the design of broad band microstrip bandpass filter is more and more important. This article analyzed the basic theory of the filter design using the uniformwidth coupling microstrip, designed and realized an S band filter whose bandwidth is 33%minia- turized the circuit structure. The final testing results indicate that the performance of this filter fulfills the design requirement.
