摘　　要：由于其优越的性能,微带线形式的各种滤波器已成为广泛使用的射频器件。本文重点研究平行耦合微带线带通滤波器的原理和设计方法,并且对其不足之处,提出了全等宽平行耦合微带线带通滤波器的设计思路。最后,结合具体应用实例,通过仿真计算,对两种形式的滤波器进行比较。结果表明全等宽平行耦合微带线带通滤波器适用带宽较宽,且结构简洁,大大降低了设计及仿真调试的复杂度。As a result of its superior performance ,microstrip lines formls each kind of filter have become the widespread use the radio frequency component.This article key research parallel coupling microstrip line bandpass filter＇s principle and design method,and to its deficiency,proposed the entire equal width parallel coupling microstrip line bandpass filter＇s design mentality. Finally,union concrete application example,through simulation computation,carries on the comparison to two formls filter.The result indicated that the entire equal width parallel coupling microstrip line bandpass filter is suitable the band width to be wide,and the structure is succinct,and reduced the design and the simulation debugging order of complexity greatly.
