ABSTRACT:
Frequency output capability of a Josephson junction digital to analog converter is increased by applying a digital data stream to a Josephson junction array including a low impedance tap in the form of a metal line of microstrip running across the top of and insulated from the array. The input end of the array and one end of the tap are commonly connected to a digital data stream source. A differential output signal is coupled from the Josephson junction array to a bandpass filter which extracts a predetermined RF frequency by means of an impedance matching transformer including a primary winding having one end coupled to the output end of the array and whose other end is coupled to the input end of the array through the low impedance tap.
