Abstract
A second-harmonic oscillator based on push-push oscillation has a pair of amplifiers for oscillation, a high frequency transmission line for connecting inputs of the pair of amplifiers to each other and connecting outputs of the pair of amplifiers to each other, and an electromagnetic coupling member disposed between the inputs and outputs of the pair of amplifiers such that it is electromagnetically coupled to the high frequency transmission line. The electromagnetic coupling member includes at least a dielectric resonator. The pair of amplifiers, high frequency transmission line, and electromagnetic coupling member form two oscillation loops which oscillate in opposite phases to each other with respect to a fundamental wave of oscillation for generating a second harmonic of the fundamental wave.
