Abstract(in English) | HTS (High-Temperature Superconductor) microwave devices applied to transmission systems have problems in terms of their power handling capability caused by surface-current concentrations on the devices. Although low power applications such as receiving filters for mobile base stations are researched and developed, HTS filters aimed at transmitters do not have same the performance as receiving filters. Reaction type filters, which do not resonate by high-power fundamental signals, are proposed. The most serious problem of the filter is currents induced on HTS resonators by fundamental signals. Some amount of the current exceeds HTS critical current density. In this report, new resonator structures consisting of the split type open-ring resonator are proposed and confirm the effect of maximum current density reduction using full-wave EM simulators. Furthermore, fundamental circuit design and feasibility of the filter are discussed. |
