| 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-supercon-ducting (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 fiat group delay is over 60 percent of the passbands. |
