摘要

本文介绍了用于多路复用网络的多极微带定向滤波器的原理和实验。传统的微带定向滤波器只有单极滤波器响应。应用阻带滤波器理论，设计并测试了两个巴特沃斯微带定向滤波器。期望的多极滤波器响应是通过阻抗逆变器连接的两个或多个相似的单级级级联来实现的。这些类型的定向滤波器是多路复用应用的理想选择，因为它们具有易于实现的特点和模块化概念的能力。此外，由于多极滤波器的特性，沿通带的响应是平坦的。

Multi-pole microstrip directional filters for multiplexing applications

Theory and experiment of multi-pole microstrip directional filters for multiplexing networks are presented in this paper. Conventional microstrip directional filters present only a single-pole filter response. By applying stopband filter theory, two Butterworth microstrip directional filters are designed and tested. The desired multi-pole filter response is achieved by cascading two or more similar single stages connected by immitance inverters. These types of directional filters are ideal candidates for multiplexing applications since they present the characteristics of easy implementation and the capacity of a modular concept. Moreover, a flat response is obtained along the passband due to the multi-pole filter behavior.
