摘要
在ADS软件的辅助下，设计了一款应用于Ka波段卫星接收机，中心频率为13GHz，带宽为2GHz的平行耦合微带线带通滤波器。应用多步优化算法解决了中心频率偏移的问题。仿真结果与指标要求吻合，可以应用与实际系统中。
With the assistance of the ADS software, design a parallel coupled microstrip line band-pass filter that can be applied in Ka band satellite receiver. The center frequency of it is 13GHz and the bandwidth is 2GHz, and the problem of frequency offset can be solved though the application of multi-step optimization algorithm. The simulation results meets the index demands, the parallel coupled microstrip line band-pass filter can be applied with the actual system.
