    • The invention relates to a frequency synthesis device (100) comprising: first means (102-112) for generating a periodic signal at a frequency f
      1 ; second and third means (114, 116) coupled to the first means and generating, from the f
      1 frequency signal, a signal S
      G corresponding to an oscillation train having a frequency equal to N.f
      1 , having a duration shorter than T
      1 = 1/f
      1 and repeated periodically at the f
      1 frequency; fourth means (118) generating, from the S
      G signal, m periodic signals S
      LO_CH1 to S
      LO_CHm having frequency spectra that each comprise a main frequency line f
      LO_CHi corresponding to an integer multiple of f
      1 , where 1 ≤ i ≤ m, the fourth means being used as a band-pass filter applied to S
      G and rejecting, from the frequency spectra of each of the periodic signals S
      LO_CH1 to S
      LO_CHm , the lines other than the main frequency line f
      LO_CHi .
