The high-temperature ceramic superconductors are granular in nature and contain several Josephson-type weak links limiting the critical current density in these materials. However, this granular superconductivity is successfully exploited by several researchers to realize some useful devices such as SQUIDs microwave detectors, and mixers at liquid-nitrogen temperature. In this communication the authors present some of the results on Video detection experiments at microwave frequencies using high-{Tc} YBCO granular thin films at 64 K. In this video mode the authors shall be interested in the output voltage from a current-biased Josephson junction that is subjected to a chopped single-frequency microwave signal.
