ABSTRACT:
An impedance-matching circuit assembly supplies a.c. power from an external a.c. source to Josephson devices. The assembly comprises resonant-line composed quarter-wave impedance conversion circuits, interconnected in a tree. The impedance-conversion circuits are assembled such that connected to the a.c. source is a circuit having a first-stage impedance, followed by two circuits having second-state impedances connected in parallel, to each of which are connected in parallel two circuits having third-stage impedances, each of which in turn is connected to supply input terminals of two of the Josephson devices.
