(In this paper, a 12-section high temperature superconducting microstrip filter for the GSM900 system, which is the most widely used in mobile communication, is proposed. Due to the selection of a new resonator structure, the filter has the advantages of compact structure and steep band edges. The filter The center frequency is 902.5MHz, and the bandwidth is 25MHz. At the test temperature of 50K, the experimental effect is in good agreement with the scheme effect.)
