Abstract
A frequency synthesis device, including: a first generator configured to generate a periodical signal with a frequency f1; a second generator, coupled to the first generator and generating from the signal with a frequency f1 a signal SG corresponding to a train of oscillations with a frequency substantially equal to N·f1, with a duration lower than T1=1/f1 and periodically repeated at the frequency f1; a third generator generating, from the signal SG, m periodical signals SLO_CH1 to SLO_CHm with frequency spectra each include a main line with a frequency fLO_CHi corresponding to an integer multiple of f1, with 1≦i≦m, the third generator operating as a band-pass filter applied to the signal SG and discarding from the frequency spectra of each of the periodical signals SLO_CH1 to SLO_CHm lines other than the main line with a frequency fLO_CHi.
