A METHOD OF SYNTHESIZING MICROWAVE FREQUENCY SIGNAL FOR MULTIPLE ATOMIC CLOCKS AND AN APPARATUS THEREOF

摘要

The present invention relates to a method and apparatus for synthesizing a frequency signal for a multi-atomic clock. A method of synthesizing a microwave frequency signal for a multi-atomic clock according to an embodiment of the present invention comprises: oscillating a reference frequency signal (S100); Generating a harmonic signal by multiplying the reference frequency signal (S200); Receiving the harmonic signal and distributing the harmonic signal to a plurality of harmonic signals (S300); A step (S400) of removing a harmonic signal component other than a predetermined center frequency signal among the divided harmonic signals; Receiving the reference frequency signal to generate a predetermined DDS frequency signal (S500); And synthesizing the predetermined center frequency signal and the predetermined DDS frequency signal to output an atomic clock frequency signal (S600). According to the present invention, a two-atomic clock can be easily driven by sharing a reference oscillator and a frequency multiplier among frequency signal synthesizers used in a plurality of atomic clocks.
