Abstract
A new type of microwave circuit for the generation of frequency-scaled voltages is investigated. The circuit is designed as a superconductin g microstrip line resonator and series arrays of Josephson tunnel junc tions located within the rf current antinodes. The circuits are design ed to obtain highly accurate voltages at low rf power level and low fr equencies of about 10 GHz. At a resonator circuit with altogether 432 junctions driven at about 10 GHz we have observed steps up to 0.25 V, the lifetime of which is about 20 minutes.
