Abstract(in English) | We have fabricated microstrip resonators at 5.7GHz using YBCO films deposited on both sides of MgO substrates and examined effects of film microstructures on power handling capability. Films with small grains (~100nm) and large critical current density showed fairly small input power dependence of surface resistance and resonance frequency. On the other hand, the films with large grains (~200nm) and small critical current density showed significant change in these properties. A qualitative discussion based on the coupled-grain model suggested that the coupling strength at the grain boundaries mainly dominates the power handling capability of the YBCO films. Band-pass filters (9.5GHz) using these double-sided YBCO films showed very small insertion loss. |
