| Abstract(in English) | YBCO thin films were fabricated on (001)LaAlO_3 substrates by using the metalorganic deposition (MOD) method which has advantages of non-vacuum, low-cost, and large-scale production of superconducting films and their microwave surface resistances were measured. The YBCO films showed preferable superconducting characteristics under the critical temperature of 90.4K with a sharp transition range. A measured microwave surface impedance of 0.13mΩ(9.98GHz,30K) is comparable with that made by sophisticated vacuum processes. Compact λ/4 coplanar waveguide (CPW) stepped-impedance resonator (SIR) bandpass filters (BPFs) were fabricated on the YBCO films. A two-stage BPF of center frequency of 5.774GHz, bandwidth of 125MHz, and insertion loss of 1.08dB is demonstrated. |
