“…From a practical point of view, a stripline SIR-BPF is not suitable for filters which require low-loss and steep cut-off characteristics, and is often applied to meet with demands which list miniaturization as the top priority [16,17]. A practical example actually in use is a two-stage BPF connecting the RF amplifier and mixer of a mobile communication terminal.…”

SUMMARYTo design superconducting microwave receivers, the surface resistance of the superconducting thin film must be considered. Therefore, a highly accurate technique for measuring the surface resistance of superconducting thin films should be established. In this paper, we propose a probe-coupled microstrip line resonator as a technique for measuring the surface resistance of superconducting thin films. In the resonator technique, the surface resistance is calculated from Q u , the unloaded Q, of the resonator. Since the microstrip line resonator searches for an accurate surface resistance of the superconducting thin film, establishing a technique that accurately determines the Q u of the resonator is crucial. We measure the Q u values of resonators fabricated from metal and superconducting thin film by a probe-coupled microstrip line resonator and describe the accuracy of Q u measurement by the probe-coupled micro-strip line resonator and the repeatability of the surface resistance measurement of a superconducting thin film.

“…The hairpin resonator can be further miniaturized to form a split-ring resonator [3]. The structure of the miniaturized hairpin resonators has also been further modified [4]. Based on the concept of folding, the most compact structure of a spiral resonator was found to be the best candidate for the miniaturization of resonators.…”
