High-temperature superconducting (HTS) reaction-type transmitting filter consisting of novel split open-ring resonators is presented. First, it is explained that reaction-type filters are suitable for high power transmission. Secondly, novel split open-ring resonators, which reduce the maximum current density while maintaining high Q-factors are proposed. Current density dispersion effects are evaluated under the same coupling coefficient. Finally, a three-pole reaction-type filter using split open-ring resonators is designed. The frequency characteristics and current distributions of the filter are investigated by the method of moments. The results predict that the filter realizes both a higher power-handling capability than transmission-type filters and a better skirt property than existing HTS dual-mode filters.
