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.
