Abstract

Proper operation of programmable Josephson voltage standard arrays depends on the uniform distribution of microwaves to a large number of Josephson junctions. Too much or too little microwave power will change the current range of a junction s constant voltage step so that an entire array of junctions will have a smaller total current margin. In this paper we discuss the important aspects of microwave power distribution including splitting the microwaves to different arrays, keeping the microwave bias uniform within an array, and minimizing the total input power to the circuit.
