| Abstract(in English) | The use of a double-strip resonator and coaxial feeding are proposed for improving the power handing capability and frequency response of high-temperature superconducting transmit band pass filter (BPF) with stripline structure. A double-strip resonator reduces the current concentration at the edges of the resonator compared with that of a conventional single strip resonator due to the increase of the effective film thickness. A double-strip two-pole dual-mode square patch BPF with a 5.0-GHz center frequency and 100-MHz (2%) bandwidth was designed. The BPF was fabricated using YBa_2Cu_3O_y thin film on an Al_2O_3 substrate. An electromagnetic simulator based on the moment method was used to design and investigate the BPF. To suppress unwanted spurious resonance near the pass band, we introduced the coaxial feeding placed a center of the double-strip resonator. The measured frequency responses of the BPF were in reasonable agreement with the simulated ones and there were no spurious resonance. Power-handling capability of the BPF was more than 31W (44.8 dBm) at 60K. |
