A high-temperature superconductor (HTS) dual-band bandpass filter (BPF) has been developed using stub-loaded hair-pin resonators. The main advantage of the filter is to allow independent control of the center frequency of the first and second bands. Flexible adjustment of the coupling coefficient can be achieved using a pair of H-shaped waveguides. We designed and analyzed a 3-pole HTS dual-band BPF. The filter was fabricated using YBa2Cu3Oy thin film on an Al2O3 substrate. The measured frequency responses of the filter agree well with those obtained during simulation.
