High Tc Superconducting Microwave Passive Components
Summary :
We have fabricated superconducting microwave passive components such as resonators, bandpass filters and delay lines with YBCO thin film conductors deposited on MgO substrates. Considerably high unloaded Q values of 12000 at 5.5 GHz was obtained with the YBCO microstrip resonator at 77 K, which indicated that the surface resistance of the YBCO thin film was 0.79 mΩ at that frequency and temperature. Excellent microwave properties were also demonstrated with the bandpass filter and the delay line. Considerably low insertion loss of about 1 dB was obtained with the 10 GHz YBCO bandpass filters at 77 K which have a various bandwidth from 0.5% to 10%. Also excellent microwave propagation was obtained with a 1.3 nsec YBCO coplanar delay line. Its insertion loss was less than 1 dB for the frequencies up to 4 GHz.
