Abstract
A series of dc SQUID radiofrequency amplifiers in the frequency range 0.1-1.1 GHz with noise temperature 0.4-2 K has been designed, fabricated and experimentally studied. For resonant input tank circuit an analytical model of noise temperature has been developed. A new effect of the output noise increasing or decreasing with changing the sign of voltage-to-flux transfer coeff 1 cient has been observed experimentally and described analytically and numerically. Application of SQUID amplifiers as IF amplifiers in SIS, Josephson, hot-electron heterodyne detectors as well as in cellular base stations has been discussed.
