Abstract

PURPOSE:To make it possible to use a cheap oscillator and make oscillation high- stability in a high frequency band of the G Hz band or more, by subjecting the frequency control means, which controls the resonance frequency of a resonator, to feedback control on the basis of difference between the frequency of the resonator and the frequency of a reference oscillator. CONSTITUTION:The frequnecy oscillated with f0/n by oscillation element 10 is stabilized to stability 1X10<-3> by resonator 9 consisting of brass. The frequency is subjected to loose coupling by coupling loop 13, and minute power of f0/n is taken out from resonator 9 and is input to feedback circuit 14 and is compared with higher harmonic of the internal reference crystal oscillation frequency, and their difference is taken out as a DC voltage from line 16 through an integrating circuit and is applied to varactor diode 8. As a result, the oscillation frequency is kept at stability + or -1X10<-5>.
