Abstract

Preliminary measurements on high-Tc superconducting resonators are reported and why they are attractive candidates for incorporation in low-noise oscillators is discussed. Some of the important contributions to oscillator noise are reviewed and show how they depend on the resonator parameters is shown. A preliminary YBa2Cu3O7/LaAlO3 resonator with a Q of 9 x 104at 6.9 GHz and 7 × 104at 3.5 GHz has been fabricated. The temperature sensitivity, power dependence and residual phase-noise will be discussed. An upper-limit on the coefficient of the 1/f component of fractional-frequency fluctuations has been measured to be-204 dB at 60 K. This is, to our knowledge, the best value reported for any high-Tc superconducting resonator.
