摘要
利用一种新型多模谐振器设计了三通带滤波器。新提出的多模谐振器采用四模谐振器加载两个开路枝节构成,能够产生六个传输极点。该滤波器经过仿真设计后进行实物加工,测试得到各通带的中心频率分别为2.55,3.83,6.00 GHz,相对应的插入损耗分别为0.9,0.7,2.3 d B,与仿真结果吻合良好。该滤波器具有回波损耗小、尺寸小的优点,可应用到现代无线和移动通信中。
An improved tri-band bandpass filter(BPF)using a novel multiple-mode resonator(MMR)was presented.The MMR was constructed by loading two open stubs in a quad-mode resonator(QMR)to generate six transmission poles.Based on the proposed MMR,a tri-band BPF with center frequencies of2.55,3.83,and6.00GHz was designed,fabricated and experimentally validated.The measurements show a low insertion loss of0.9,0.7and2.3dB at each resonant frequency,and have a good agreement with the simulation results.When compared with previous publishedwork,the proposed filter also has advantages such as low return losses and compact size.This tri-band BPF is expected to be used for modern wireless and mobile communications.
