摘要

在本文中;提出了由发夹状阶跃阻抗滑环谐振器(SISRs)组成的紧凑滤波器。研究了两种构型。其中一个用于实现四极准椭圆函数带通滤波器。另一个是通过消除第一个的交叉耦合路径来构造的。与传统开环方形谐振器相比;每条边的长度减少了2046。除此之外，杂散模式被移动到更高的频率。

Hairpin-shaped step-impedance slip-ring filters

In this paper; compact .filters composed of hairpin-shaped step-impedance slip-ring resonators (SISRs) are presented. Two configurations were studied. One is used to implement a four-pole quasi-elliptic function band-pass .filter. Tlze other one is constructed by eliminating the cross coupling path .from the ,first one. Compared with the traditional open loop square resonator; there is a 2046 reduction in length for each side. Besides that, the spurious mode is moved to higher frequencies. .
