Abstract
Techniques that facilitate a superconducting combiner or separator of DC-currents and microwave signals are provided. In one example, a device includes a direct current circuit and a microwave circuit. The direct current circuit comprises a bandstop circuit and provides transmission of a direct current signal. The microwave circuit provides transmission of a microwave signal. The microwave circuit and the direct current circuit that comprises the bandstop circuit are joined by a common circuit that provides transmission of the direct current signal and the microwave signal.
