平行耦合微带线带通滤波器的设计仿真与测试

摘要

在ADS软件的辅助下，设计出了一种应用于11 GHz频段数字微波传输系统室外单元，中心频率为11 GHz，带宽为1.5 GHz的平行耦合微带线带通滤波器，并进行了实物测试，测试的S参数与仿真优化结果及指标要求吻合较好。%With the aid of ADS (Advanced Design System),a parallel coupled microstrip bandpass filter is designed, which can be applied in ODU of digital microwave transmission system with 11 GHz frequency band. The centre frequency of the filter is 11 GHz,the bandwidth is 1.5 GHz. The object was tested and the performance of S parameter agree well with the results of the simulation optimization and the design indexes.
