摘要
介绍了一种终端短路式圆杆交指带通滤波器的设计方法。根据交指滤波器的准确设计理论获得的圆杆自电容和互电容,结合图表得到了滤波器的最初尺寸,并结合微波电路仿真软件对其进行了优化、仿真。仿真结果和实际测试的结果比较一致,证明了设计方法的可行性。
The design method of a microwave interdigital band - pass filter is presented. First, the selfcapacitor and mutual capacitor of the interdigital band - pass filter is obtained in according with the exact design theory of the interdigital bandpass filter. Then with the aid of micrwave CAD software , the interdigital bandpass filter is optimized and simulated . The simulation result agrees with the measurement one, which proves the method is valid.
