A frequency generator generating an output signal having a predetermined output frequency, including: a local oscillator generating a reference signal having a reference frequency, and a phase-locked loop, the phase-locked loop provided with a controlled oscillator generating the output signal having the output frequency as a function of the signal at its input, and a comparator providing a signal to the controlled oscillator as a function of a phase and/or frequency comparison of a first comparison signal based on an input signal applied to a first input of the phase-locked loop with a second comparison signal based on the output signal, the frequency generator further including at least one harmonic generator generating, from the reference signal, a harmonic signal including a predetermined harmonic of the reference signal, the frequency generator applying the harmonic signal of one of the harmonic generators to the first input of the phase-locked loop.
