Abstract
Superconducting granular bridges of Y-Ba-Cu-O show the AC Josephson effect. A spectral detector has been devised with a granular bridge as the sensor, which is coupled to a microstrip line. The device has been operated in the millimeter-wave range (Ka-band) in liquid nitrogen at a temperature of 77 K. The DC V(I) characteristics of a granular bridge for a millimeter-wave signal of f/sub 1/=35.5 GHz at various power levels are presented.<>
