Abstract

PURPOSE:To simplify, make small and light the synchronism oscillator, by constituting the injection synchronism oscillator through the connection of two reactance circuits to the gate and source of FET and injecting the signal of frequency-divided or high frequency near the self-running frequency of the oscillator. CONSTITUTION:In the injection synchronism oscillation system using FET1, the gate terminal 2 of FET1 is connected to the reactance circuit 3, the source terminal 4 is connected to the reactance circuit 5, and the drain terminal 6 is connected to the impedance converstion circuit 7. Further, the circuit 7 is connected to the load 9 via the filter 11 having the pass band at frequency f0 and also connected to the reference signal generator 10 via the filter 12 having pass band at the frequency f1. The circuits 3 and 5 connected to FET1 constitute the injection synchronism oscillator and the signal having the frequency near the frequency divided or harmonics of the selfrunning frequency of the oscillator is taken as the injection signal, simplify the oscillator with small size and light weight.
