摘要
本文叙述了一种新型的窄带带通滤波器的设计方法。采用直接耦合1/4波长同轴谐振器制成的窄带带通滤波器具有体积小,带内插损较小,调试简单等特点,可广泛用于数字通信设备中。本文同时给出了采用介电常数εγ为38的介质设计制作成的中心频率为1370MHz,三分贝带宽为30MHz滤波器的试验结果。理论值与实验结果较相吻合。
This paper describes a new design method for a narrow bandpass filter. The filter utilizing a direct-coupled λ/4-coaxial resonator can provide high functions, especially lower insert-loss, small dimensions, and easily-adjusted ability. It can be widely used in digital communication. Finally the experimental results of the filter operating at 1370MHz are given, which is in excellent agreement with the theory.
