摘要:
利用枝节加载开环多模谐振器和非对称耦合线,设计了一种紧凑型三通带带通滤波器.该多模谐振器在通带内能产生3个奇模和3个偶模.运用奇偶模理论对该谐振器的特性进行分析,其通带边缘的多个传输零点,可显著提高滤波器的选择性和阻带特性,且通过调节非对称耦合线位置,还可以实现对传输零点的有效调控.该滤波器可应用于全球移动通信系统 GSM、全球定位系统和数字蜂窝系统 DCS.
Abstract:
A compact tri-band bandpass filter(BPF)using stub-loaded open-loop multi-mode resonator and asym-metric coupling lines has been presented. The multi-mode resonator can generate three odd modes and three even modes in the desired passband. Odd-even mode theory has been used to analyze the characteristics of the resonator, there are several transmission zeros(TZ)near the passband edge,and they can improve selectivity and stopband suppression. Meanwhile,transmission zeros can be controlled by tuning the asymmetric coupling lines. The filter has been applied for GSM,GPS and DCS.
