Abstract
A planar harmonic high frequency oscillator comprises a pair of amplifiers for oscillation, a micro-strip line for connecting between inputs of the pair of amplifiers and between outputs of the amplifiers, a slot line disposed between the inputs and the outputs of the pair of the amplifiers for electromagnetically coupling with the micro-strip line, an output line connected to the micro-strip line at a position at which the micro-strip line traverses the slot line between the inputs or outputs of the pair of amplifiers, and an electronic device for connecting conductors on both sides of the slot line, and for controlling an electromagnetic wave field of the slot line in response to a control signal applied thereto. Two oscillation systems which oscillate in opposite phases with respect to the fundamental wave of oscillation are formed to generate an even-order harmonic of the fundamental wave.
