Abstract

The present disclosure provides a frequency generator, and belongs to the technical field of communications. The frequency generator provided by the present disclosure includes: N stages of mixing modules and N stages of comb spectrum generation modules. Each of the comb spectrum generation modules is configured to provide a mixing module in a same stage as the comb spectrum generation modules with one stage of fundamental signal group generated according to a second reference signal; and different stages of fundamental signal groups are generated based on different second reference signals. A 1^st-stage mixing module generates a 1^st-stage mixed signal according to a 1^st-stage fundamental signal group and a first reference signal, and the 1^st-stage fundamental signal group includes a plurality of harmonic signals with a first frequency as a fundamental frequency.
