Abstract
A high-frequency oscillator circuit designed to efficiently output fundamental and second harmonic waves. A second harmonic resonance circuit is inserted between bases of a pair of transistors having collectors connected to each other. Each of a pair of capacitors is inserted between the base and an emitter of the corresponding one of the pair of transistors, and each of another pair of capacitors is inserted between the emitters of the transistors. Further, a pair of fundamental wave output terminals for outputting fundamental waves are respectively connected to the bases of the transistors, and a pair of second harmonic output terminals for outputting second harmonic waves are respectively connected to a connection between the second pair of capacitors and a connection point between the collectors of the pair of transistors.
