Challenges of Josephson Junction Arrays for ac Voltage Generation by Microwave Pulse Power Modulation

A.S. Katkov, A.M. Klushin, G.P. Telitchenko, R. Behr, J. Niemeyer
2005 IEEE transactions on applied superconductivity  
In this paper, arrays of SINIS Josephson junctions were investigated which produce a 1 V voltage step under irradiation at a frequency of the order of 70 GHz.  ...  This allows the generation of a 1 V voltage pulse by switching the microwave power at constant dc bias current.  ...  This demand requires very fast transient times of better than 100 ns and thus to very stringent conditions for the parameters of programmable Josephson arrays.  ...
