一种新颖的微带带通滤波器的设计

Design of One Novel Microwave Bandpass Filter

摘要:

介绍一种选择性介于切比雪夫滤波器与椭圆滤波器之间、物理上也易于实现的带通滤波器,给出了它的传输函数,依此在切比雪夫滤波器设计参数的基础上进行该滤波器的综合,然后用耦合谐振滤波器的理论与公式来分析该滤波器的频率响应。该滤波器采用新颖的开环谐振器耦合结构来实现,结果在保持很好的线性与较高的矩形系数的同时,体积也做得较小。

One novel microwave bandpass filter is introduced in this paper.This filter,which is easy to be implemented physically,has the skirt selectivity intermediate between Chebyshev filters and the elliptic-function filters. The transfer function of the filter
