Abstract :
The use of high-transition-temperature (T/sub c/) superconducting resonators to stabilize oscillators operating between 1 and 10 GHz is discussed. Measurements of surface resistance are presented and related to the resonator quality factor (Q). Projections of resonator Q and oscillator phase noise are discussed. Improved materials should offer a greater than 20-dB reduction in noise over competing technology. The implications of flicker noise in reaching this level of performance are discussed, and preliminary measurements of flicker noise in the high-T/sub c/ materials are reported.<>
