Synthesis and design of HTS diplexers

A design approach for high temperature superconducting(HTS) diplexers was presented in the paper.The diplexer consisted of a common node and two bandpass filters.The common node was realized by a half wavelength open-loop resonator and used to combine the two channel filters,as well as a susceptance annulling network to eliminate the influence between the two filters.Each channel filter consisted of six hairpin resonators with folded coupled lines and a cross microstrip line realizing cross-coupling.The working frequency of the HTS diplexer was in the C-band.The simulation results were agreement with the theoretical results,which verifies the effectiveness of the design approach.
