1. A method for reducing phase noise in an oscillator operational in the millimeter wave and microwave range, comprising providing a lumped element active circuit including an active element with a negative resistance, providing a lumped element resonator circuit coupled to said active circuit and affording resonant circuitry in combination therewith, reducing phase noise by enhancing Q of said resonant circuitry by reactively terminating fundamental frequency oscillation and increasing stored fundamental frequency energy in said resonant circuitry.
