Abstract
The responsivity and the noise equivalent power (NEP) of Josephson junctions in video detection of microwave and millimeter‐wave radiation have been calculated. The sensitivity to radiation is assumed to be limited by the rounding of the voltage‐current curve due to thermal noise of both the source resistance and the junction resistance. The calculated NEP is at least several tens of times better than any experimentally established.This publication has 5 references indexed in Scilit:
