ABSTRACT:
A broadband YIG-tuned oscillator is disclosed that has both series and parallel feedback provided by a YIG sphere. The oscillator includes a transistor capable of driving a load coupled to a first port of the transistor, a reactive feedback element coupled to a second port of the transistor, a YIG resonator, and coupling means for coupling the YIG resonator to both a third port of the transistor and to the first port of the transistor.
