PROBLEM TO BE SOLVED: To provide a high-frequency oscillator capable of suppressing unwanted oscillation. SOLUTION: The oscillator is provided with a resonance circuit 1 for deciding an oscillation frequency, an active circuit 2 consisting of a field-effect transistor (FET) 21 connected to the resonance circuit and a reflection circuit 22 connected to the FET 21 to reflect a part of oscillation power to the FET side, and an output terminal 3 connected to the reflection circuit 22 to take the oscillation power. The reflection circuit 22 is composed of two reflection stubs 23a, 23b. COPYRIGHT: (C)2005,JPO&NCIPI
