Abstract
High-temperature superconducting arrays of Josephson junctions have be en fabricated and tested as millimeter-wave oscillators at 77 K, Power levels in the microwatt range have been detected in the range of 90-1 60 GHz from arrays using from 350 to almost 60 000 YBa2Cu3O7 junctions . Monolithic log-periodic spiral antennas as well as quasioptical reso nators have been used to enable power coupling. The arrays were also f ound to be bias tunable over ranges limited by the receiving apparatus .
