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.

L'invention concerne un résonateur et un filtre accordables supraconducteurs pouvant être mis en application dans une plage étendue de fréquences, y compris la plage de fréquences MHz. Dans un mode de réalisation, deux résonateurs supraconducteurs (102, 103) sont placés sur une première surface d'un substrat (101) et un circuit de commutation (104) est couplé à au moins un des résonateurs (102, 103), de sorte que le circuit de commutation (104) réagit à un signal possédant au moins un premier et un deuxième état, et, de ce fait, conduit un des premier et deuxième résonateurs (102, 103) jusqu'à un état non supraconducteur, ce qui provoque l'accord des résonateurs et du filtre.
