摘　　要：基于悬置线交指带通滤波器通带内插入损耗比较小,具有很高的选择性和很大的带外衰减,常应用于无线电收、发接收机以及雷达通信系统中.将综合设计法和微波电路仿真软件ADS相结合,设计悬置线终端开路式交指带通滤波器.根据交指滤波器的理论得到每个杆的归一化单位长自电容和两相邻杆的归一化单位长互电容,得到滤波器的最初尺寸.利用ADS软件建模、仿真、优化调整,最后得到该滤波器的几何参数尺寸终值.该设计方法简单,适合工程应用.The interdigital band -pass filter based on suspended line with low pass -band insertion, precise selective and high out - band attenuation, which is often used in wireless transceiver and radar communication system. In order to design band - pass filter which hangs to place the open - circuit type of the line terminal, the traditional calculate method is combined with the microwave ADS software, the self-capacitor , mutual capacitor and the initial value of the geometry parameter of the interdigital band - pass filter are obtained according to the exact design theory of the interdigital band - pass filter, by building model, simulation, and optimization adjustment, the final value of the geometry parameter for the filter is gotten. The method is simple in designing filter and easily available for engineering applications.
