The even- and odd-mode frequencies and the coupling strength of the proposed resonators can be independently designed and adjusted. A dual-feedline structure is used to meet the required external couplings of the 2 passbands. Thus, both the center frequencies and the bandwidths of the 2 passbands can be independently controlled. A 6-pole dual-band filter with the passbands of 3300∼3600 MHz and 4800∼5000 MHz is successfully designed using the proposed method and fabricated with YBCO/MgO high-temperature superconducting (HTS) wafer. The measured results of the filter exhibit high performance and match well with the simulations. The measured insertion losses are less than 0.2/0.3 dB, and the return losses are greater than 15/14 dB for the lower/upper passbands, respectively. The out-of-band rejection is greater than 68 dB up to 12 GHz. Citing Literature Volume28, Issue5June 2018e21291 RelatedInformation
