14 Claims

1. A frequency generator, comprising: N stages of mixing modules and N stages of comb spectrum generation modules; wherein, N≥2;

each of the comb spectrum generation modules is configured to provide a mixing module in a same stage as the comb spectrum generation module with a 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 is configured to generate 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 comprises a plurality of harmonic signals with a first frequency as a fundamental frequency; and

an i^th-stage mixing module is configured to generate an i^th-stage mixed signal according to an i^th-stage fundamental signal group and a (i−1)^th-stage mixed signal; the i^th-stage fundamental signal group comprises a plurality of harmonic signals with an i^thfrequency as a fundamental frequency; and 2≤i≤N.
