Title:
RUBIDIUM ATOMIC OSCILLATOR
Document Type and Number:
Japanese Patent JPH04238414
Kind Code:
A
Abstract:
PURPOSE: To save the power of a rubidium atomic oscillator and to simplify adjustment.
CONSTITUTION: A microwave signal supplied to an opticalmicro wave resonance part 21 is generated based on an output signal from a voltage controlled crystal oscillator 23 by using a phase synchronous loop consisting of a phase comparator 14, a low pass filter 15, an adder 16, a voltage controlled oscillator 17 and a frequency divider 13 and a frequency synthesizer 11 outputting the frequency signal of a prescribed frequency to the adder 16 based on the output signal from the voltage controlled crystal oscillator 23.
