The power handling capability and frequency response of transmit high-temperature superconducting stripline filter with shuttle-shape resonators were investigated. A cascaded quadruplet (CQ) design is used to produce a pair of attenuation poles for obtaining sharp cutoff characteristics. The shuttle-shape resonators improve power handling and out-of-band rejection. An electromagnetic simulator based on the moment method was used to design a four-pole SL CQ filter with shuttle-shape resonators (5.0-GHz center frequency and 100-MHz bandwidth). The filter was fabricated using YBa2Cu3O7-d thin films on an Al2O3 substrate and was formed Au ground plane. The filter showed good frequency response. From the result of the power-handling capability, the filter showed a liner property until 7.9 W.
