The Development of the Superconducting Cavity Stabilized Oscillator,

A very high stability microwave oscillator system was developed which has a high Q superconducting cavity as its frequency determining element. In stabilized oscillator SCSO, the rf power is generated by a Gunn-Effect oscillator whose frequency is electronically tuned by a varactor diode. An intermediate frequency discriminator is used to produce a feedback voltage which maintains the oscillator at the center of the cavity resonance. An improved stabilization system is now reported which has higher short term stability.
