| Abstract: | In this paper,an ultra-wide band high temperature superconducting(HTS) filter with 6 pair of quarter-wavelength short-circuited stubs was presented.The equivalent model,theoretical result,and the simulated result of the filter were demonstrated.The desired filter was designed and fabricated using double-sided DyBa2Cu3O7 thin films on 2-inch diameter and 0.5mm thickness MgO wafer.The center frequency of the filter was 4.2GHz,and the fabricate band wide(FBW) was 50%.The measurement results show that the respo... |
