In this paper, a high temperature superconducting dual-mode microstrip filter with high power handling capability for TD-SCDMA communication system was designed, the theory, the equivalent circuit, coupling matrix, simulated performance and the measured results were presented. The filter was manufactured on the double-sided HTS DyBCO film on a LAO substrate of 0.5mm thickness. The center frequency is 2017.5MHz, the bandwidth is 15MHz, and the power handling capability is more than 10Watts.
