FREQUENCY GENERATOR FOR RADIO FREQUENCY EQUIPMENT AND METHOD FOR GENERATING AN OUTPUT SIGNAL

摘要

The invention relates to a frequency generator for a radio frequency equipment for generating an output signal having a predetermined output frequency (F), the frequency generator comprising: a local oscillator (3) for generating a reference signal having a frequency of reference (Fref), and a phase locked loop (5), the phase locked loop being provided with a controlled oscillator (25) generating the output signal having the output frequency (F) as a function of a signal at its input, and a comparator (21) providing a signal to the controlled oscillator (25) according to a comparison (C) of phase and / or frequency of a first comparison signal (Fcomp1) based on an input signal applied to a first input (16) of the phase-locked loop (5) with a second comparison signal (Fcomp2) based on the output signal, the frequency generator (1) comprising in besides at least a harmonic generator (7) adapted to generate, from the reference signal, a harmonic signal having a predetermined harmonic (F) of the reference signal, the frequency generator being adapted to apply the harmonic signal of one of the harmonic generators at the first input (16) of the phase locked loop (5). In addition, the present invention relates to a method for generating an output signal.
