In this article, we present forward-coupled microstrip filters designed using an integral-equation-based field solver, and fabricated in high-temperature superconducting (HTS) thin films. Two designs were studied, one a nine-pole bandpass filter at 9

A 5-b high-temperature-superconductive digital instantaneous frequency-measurement (DIFM) subsystem has been constructed for the determination of the frequency of unknown signals over a 500-MHz bandwidth, centered on 4 GHz, with a resolution of +or-7

We report narrowband microstrip filters with low insertion loss and high power-handling capabilities made from high-temperature superconducting (HTS) films. One interdigital filter that uses HTS films for both the microstrip and ground plane has 0.6%
