OXIDE SUPERCONDUCTING MICROWAVE DEVICE

摘要

PURPOSE:To realize the oxide superconducting microwave device with high performance and high reliability in which the frequency adjustment or the performance adjustment at mount is facilitated. CONSTITUTION:A thin fluororesin thin film 18 is filled in a gap 16 between an upper board including an upper ground lane 12 and an intermediate board 13 including a center conductor 11 to assemble the strip line structure of the oxide superconducting microwave device. Thus, an undesired gap for close adhesion is eliminated by smoothing a mechanical contact face between the upper board 14 and the intermediate board 13. Since the gap 16 is filled by using the fluororesin thin film 18 having a larger dielectric constant than that of air, a change in the effective dielectric constant around the center conductor 11 is suppressed.
