| Abstract: | This paper studied the precise design of HTS microtrip bandpass filter. As an example we designed a 5-pole hairpin HTS microstrip bandpass filter for GSM mobile communications application. The center frequency of filter is 1747.5MHz, and the bandpass width is 75MHz. Simulated and optimized performance showed good frequency response. The filter has less then 0.1dB passband ripple and better than 15dB return loss. It accorded with the original design request well. |
