  • Abstract
    A thallium-based high-temperature superconducting cavity is developed to stabilize an X-band microwave oscillator. The 10-GHz cavity has unloaded Q values of 5.7 × 104 at 77 K and 1.5 × 105 at 20 K. A 10-GHz free running oscillator stabilized by the cavity has single sideband phase noise of -82, -114, and -132 dBc/Hz at 1, 10, and 100 kHz frequency offset from the carrier, respectively
