Abstract: An improved microwave oscillator wherein the oscillator includes a resonator assembly provided with a movable resonator member for varying the frequency response of the oscillator and which further includes a transistor, the improvement including means for varying the electrical coupling between a lead of the transistor and the resonator assembly to provide optimum coupling between the transistor lead and the resonator assembly for maximum power output; means for compensating for variations in frequency response of the oscillator upon different transistors being positioned different distances from the resonator assembly; coupling means electrically associated with the transistor to assure proper coupling between the transistor and the resonator assembly at the low frequencies; means for providing additional feedback to the transistor to assure sufficient feedback to sustain low frequency oscillation of the transistor which is typically chosen and designed for high frequency oscillation; and a flexible linkage interconnected between the resonator movable member and the apparatus for moving the resonator movable member whereby any lateral misalignment between structural members and apertures is compensated for.
