Filed: 1988-11-24
Abstract: PURPOSE:To improve the stability of an oscillating frequency by comparing the oscillating frequency of an oscillator with a reference signal, and controlling a bias voltage which is applied to the control terminal of a positive element for oscillation, by negative feedback operation. CONSTITUTION:The oscillating frequency to be induced to a first microstrip line 2 is supplied through a capacitor 20 for direct current block to a divider 21 and a divided frequency is compared with the reference frequency of a reference oscillator 22 by a phase comparator 23.
