TUNABLE HIGH TEMPERATURE SUPERCONDUCTOR RESONATOR AND FILTER

摘要

This invention pertains to a superconducting tunable resonator and filter device operable over a broad range of frequencies including the MHZ frequency range. In one embodiment, two superconducting resonators (102, 103) are disposed on a first surface of a substrate (101) and a switch circuit (104) is connected to at least one of the resonators (102, 103) such that the switch circuit (104) is responsive to a signal having at least a first and second state which causes the switch circuit (104) to drive one of the first and second resonators (102, 103) into a non-superconducting state, thereby effecting tuning of the resonators and filter.
