Abstract
A harmonic oscillator comprises a transmission line resonator in which an oscillation frequency depends on an electrical length of a transmission line and both ends of the transmission line are electrical open ends; an active element for oscillation as a negative resistance connecting to the transmission line resonator; an output line connected to a midpoint portion of the transmission line resonator; and electrical and/or physical suppressing means for suppressing a voltage displacement distribution of second harmonic among the even-order harmonics. The suppressing means is provided at a position which is at least a minimum voltage displacement portion for the second harmonic between the midpoint portion and either ends of the transmission line resonator.
