摘要：

High-temperature superconducting arrays of Josephson junctions have been fabricated and tested as millimeter-wave oscillators at 77 K, Power levels in the microwatt range have been detected in the range of 90-160 GHz from arrays using from 350 to almost 60 000 YBa2Cu3O7 junctions. Monolithic log-periodic spiral antennas as well as quasioptical resonators have been used to enable power coupling. The arrays were also found to be bias tunable over ranges limited by the receiving apparatus.
