摘要:

滤波器作为射频收发机中不可缺少的关键器件,双频或多频滤波器已成为研究重点。文中提出了一种新型的“凸”型谐振结构,利用该谐振结构研制出一种双频带滤波器,并对其谐振结构进行了建模仿真。采用弱耦合的方式对结构的谐振模式进行分析,在该谐振器下方中央位置加载一段开路枝节,对该谐振器选取合适的耦合方式进行馈电,研制出一种新型双频滤波器,并进行滤波器实物加工和测试,验证了该方法的正确性。

关键词: 耦合线, T型滤波器, 频率响应

Abstract:

Filters are essential components in modern communication system,and the dual or multi-frequency filter has become the focus of study.A new type of resonator is put forward,and its mode is analyzed.A dual-band filter is made by adding an open stub at the bottom of the resonator in weak coupling by proper coupling method.The experimental results of the fabricated filter measured by network analyzer agree well with the simulation results.

Key words: parallel coupled line;t-type filter;frequency response
