Abstract
A microwave tuned oscillator utilizing a ferromagnetic thin film resonator comprises: a) a microwave resonator () comprising a ferromagnetic thin film resonance plate () such as a disc-shaped YIG crystal placed on a microwave integrated circuit (), such as a half-wavelength strip-line resonator, b) bias magnetic field means () for applying a bias magnetic field perpendicular to the ferromagnetic thin film resonance plate (), c) an active element for oscillation (), a reactive feedback element () and a load () controlled by the microwave properties of the ferromagnetic thin film resonance plate () through a load feedback loop (), and d) an overall positive feedback loop () connected between the active element for oscillation () and the microwave resonator () to cause a sustained oscillation to build up at one of parametrically excited resonances of the ferromagnetic thin film resonance plate ().
