High temperature superconducting (HTS) Y-Ba-Cu-O (YBCO) films were prepared on MgO polycrystal substrates by the sol-gel process. The temperature dependence of the surface resistance (Rs) of the YBCO film around 9.9 GHz was observed. YBCO coplanar waveguide (CPW) quarter-wavelength (λ/4) resonator operating around 2 GHz was fabricated using the sol-gel film, and RF properties of the YBCO CPW resonator was compared with that of normal metal resonator. The temperature and stored energy dependence of the transmission characteristics were observed in order to examine the temperature and power handling capabilities of the HTS resonator. The quality factor (Q0) of the YBCO CPW λ/4 resonator increased significantly as the stored energy decreased, whereas the resonant frequency hardly changed. Moreover, the magnetic penetration depth at 0 K (λ0) was also estimated.
