    摘要： Fabrication of superconducting devices that combine or separate direct currents and microwave signals is provided. A method can comprise forming a direct current circuit that supports a direct current, a microwave circuit that supports a microwave signal, and a common circuit that supports the direct current and the microwave signal. The method can also comprise operatively coupling a first end of the direct current circuit and a first end of the microwave circuit to a first end of the common circuit. The direct current circuit can comprise a bandstop circuit and the microwave circuit can comprise a capacitor. Alternatively, the direct current circuit can comprise a bandstop circuit and the microwave circuit can comprise a bandpass circuit. Alternatively, the microwave circuit can comprise a capacitor and the direct current circuit can comprise one or more quarter-wavelength transmission lines.

    摘要： An irreversible circuit element includes first and second high pass isolators each including first and second center electrodes intersecting with and being insulated from each other on a ferrite to which a direct-current magnetic field is applied with a permanent magnet. One end of the first center electrode is an output port and the other end thereof is an input port, and one end of the second center electrode is another output port and the other end thereof is a ground port. A pass frequency band of the first isolator is higher than a pass frequency band of the second isolator. Respective output portions of the first and second isolators are electrically connected and defined as one output terminal, and a low pass filter LPF is inserted between the output terminal and the output port of the second isolator.

    摘要： A non-reciprocal circuit element includes a ferrite, a first central electrode and a second central electrode that are arranged on the ferrite so as to cross each other in an insulated state, and a permanent magnet configured to apply a DC magnetic field to a portion where the first and second central electrodes cross each other. One end of the first central electrode defines an input port and the other end thereof defines an output port. One end of the second central electrode defines the input port and the other end thereof defines a ground port. A resistance element and a capacitance element which are connected in parallel with each other are connected in series between the input port and the output port. A switching capacitance unit configured to switch a capacitance is connected in parallel with the resistance element between the input port and the output port.
