We report on high frequency experiments with mesa structures patterned on Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+y/ single crystals (BSCCO). Due to the intrinsic Josephson effect between adjacent CuO/sub 2/ bilayers these mesas form stacks of 100 to 500 Josephson junctions. The ac-Josephson effect was investigated in the frequency range between 6 GHz and 120 GHz. We focus our interest on possible applications of intrinsic Josephson junctions as flux-flow oscillators and high-frequency mixers. These components form the essential parts of an integrated mm-wave receiver in BSCCO technology.
