Abstract
An injection-locked high-frequency oscillator has an annular transmission line, and m (m>1) units of oscillating amplifiers, and is provided with an oscillation closed loop formed with the transmission line and the oscillating amplifiers, the oscillating frequency thereof being determined by an electric length of line of the oscillation closed loop. When n≧1 is defined, and when the wavelength corresponding to the oscillating frequency is defined as &lgr;, the electric line length from any one oscillating amplifier to the neighboring oscillating amplifier is set to be n&lgr; by taking delay time due to the oscillating amplifiers into consideration, and further into in-phase points on the oscillation closed loop, synchronizing signals having, respectively, a frequency that is 1/mn of the oscillating frequency are injected.
