Outline of Final Research Achievements |
A high-temperature superconducting (HTS) tri-band bandpass filter (TBPF) is developed for next generation cellular base station. The TBPF constructed with dual-band bandpass filter with stub-loaded meander-line resonators and single-band bandpass filter with step-impedance resonators . The center frequencies are 3.5 GHz, 4.25 GHz and 5.0 GHz. We designed and analyzed a 4-pole and 7-pole HTS TBPF. The 4-pole TBPF was fabricated using YBa2Cu3O7 thin film on r-Al2O3 substrate. The measured frequency responses of the filter match well with the simulation one.
