ABSTRACT:
A superconducting active lumped component for microwave device application including a dielectric substrate, a first superconducting portion of an oxide superconductor provided on said dielectric substrate, an insulator layer formed on the first superconducting portion and a second conductive portion arranged on the insulator layer in which the conductivity of the first superconducting electrode and the dielectric property of the insulator layer can be changed by a dc bias voltage applied between the first and the second conductive portion so that capacitance and/or inductance and/or microwave resistance can be changed.
