摘要

本文介绍了一种利用复传输零点设计自均衡双通带滤波器的方法

并用开环微带谐振器实现该滤波器电路.利用全波仿真软件

设计了一个12阶双通带自均衡高温超导薄膜微带滤波器.仿真结果显示该滤波器两个通带分别为2.631~2.679GHz

2.781~2.829GHz

阻带为2.681~2.779GHz

平坦的群时延占整个带宽60%以上.

Abstract

We report a method for designing self-equalized dual-passband filters by using complex transmission zeros.The filter is realized by utilizing open-loop microstrip resonators.Using full-wave EM software

a 12-pole high-temperature-superconducting (HTS) filter which has two self-equalized passbands is designed.The two passbands (2.631~2.679GHz and 2.781~2.829GHz) are separated by a stopband (2.681~2.779GHz).The result indicates that the flat group delay is over 60 percent of the passbands.
