Abstract

PURPOSE:To stabilize an oscillation frequency by providing resonators which resonate to frequencies higher and lower than the oscillation frequency respectively and applying the output voltage from both resonators to a differential amplifier to generate a feedback signal. CONSTITUTION:The output from stabilized oscillator 10 is inputted to resonators 15 and 16 which resonate to frequencies higher and lower than the oscillation frequency respectively through couplers 13 and 14. Output voltages can be obtained from these resonators and are applied to differential amplifier 19. If the oscillation frequency is lowered, the output voltage from resonator 16 is increased, and as the result, control is so performed that the oscillation frequency of oscillator 10 may be raised by the output voltage of differential amplifier 19.
