Multiplexers have been fabricated using high-temperature superconductors (HTS). Superconducting YBa2Cu3O7-x films were deposited on MgO, a substrate by using pulsed laser deposition (PLD). A conventional photolithographic method was used to produce the superconducting multiplexer pattern. Epitaxial YBCO films with c-axis orientation were grown on MgO (100) substrates. Superconducting transition temperatures were measured at 89 K. Simulated results of the superconducting multiplexer consisting of hairpin type filters show an insertion loss of 1.2 dB. The measured frequency response of superconducting multiplexer was compared with the simulation results.
