摘要:
提出了一种基于短开路耦合器加载的宽带带通滤波电路. 该滤波电路通过在输入和输出端口之间,并连加载短路耦合微带谐振器和开路耦合微带谐振器实现5个传输极点和3个传输零点的带通选择特性. 对所提出的短开路耦合谐振器进行了奇偶模理论分析,揭示了其传输零极点形成的物理机理. 最后,对所提出的滤波电路进行了加工测试. 测试结果表明,所提出的宽带滤波电路能够在2.0～4.2 GHz频率范围内实现 3 dB 带通传输,工作相对带宽为73%,仿真和实测结果吻合较好.
Abstract:
A wideband bandpass filter circuit is proposed in the paper by loading the shorted/open coupled line resonators. Five transmission poles and three transmission zeros are obtained by parallel loading the shorted and open coupled line resonators. To give a physical insight,the shorted and open coupled line resonators are analyzed with the even-/odd-mode theory. Finally,the designed bandpass circuit is fabricated and measured. The measured results show that a 3 dB frac-tional bandwidth of 73% is obtained and its operating frequency range is from 2.0 GHz to 4.2 GHz,which suggests a good agreement with the simulated one.
