Observation of nonlinearity in dual-band superconducting filter using spirally asymmetric stepped-impedance resonators

In this paper, a compact dual-band high-temperature superconducting (HTS) bandpass filter is demonstrated for observing the nonlinear phenomena. Various theoretical models are applied to investigate the equivalent circuits of the proposed superconducting transmission line. To verify this methodology, the measured temperature dependence (from 65 K to 100 K… CONTINUE READING
