An HTS Five-channel Multiplexer Based on Common-coupled Resonator

A high temperature superconducting (HTS) five-channel multiplexer is designed based on common-coupled resonator structure. The center frequencies of multiplexer are 807. 5 MHz, 810. 5 MHz, 813. 5 MHz,816. 5 MHz and 819. 5 MHz respectively, and the bandwidth of each channel filter is 1 MHz. The multiplexer is fabricated using double-sided HTS DyBCO thin film on 3-inch diameter and 0. 5 mm thickness MgO wafer. The equivalent circuit, theoretical result, coupling matrix, and the simulated result with Sonnet software have also been demonstrated. The measurement results show that the response of practical multiplexer is in good agreement with that of simulated results and theoretical analysis.
