| Abstract: |
| 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. |
