Multi-band frequency synthesizer including a first oscillator (2) with voltage-controlled frequency, slaved in frequency by a regulation loop (4, 7, 8, 9) receiving a frequency datum signal (SC) and including a phase comparator (7) receiving the frequency of the oscillator (2) after passing through a divider (8) of rank R, a synthesizer (1) including a second similar oscillator (3), capable of being substituted for the first oscillator (2) and controllable by this regulation loop (4, 7, 8, 9), the gain of the phase comparator (7) being controlled in such a way as to compensate for the variations of the gain in terms of frequency of the loop as a function of the rank R. <IMAGE>
