TY  - JOUR
AB - The origins of phase noise in oscillator systems are reviewed. A simple self-excited 7. 5Ghz oscillator incorporating either a conventional metal cavity resonator or a high temperature superconducting (HTS) cavity has been produced. Comparative measurements made at 77K demonstrate significant improvements in the close-to-carrier noise performance of the oscillator incorporating the HTS cavity; lOdB at a 10kHz offset rising to more than 25dB at a lOHz offset. The unloaded Q of the HTS cavity doubled to >ltf on cooling from 77K to 64K suggesting that further improvements in noise performance could be achieved. © 1997 IEEE.
