Abstract
Un synthétiseur RF (radiofréquence) (200) comprend un VCO (oscillateur contrôlé par tension) (220) qui émet un signal de sortie à la fréquence souhaitée (FVCO) et, couplé au VCO, un diviseur de fréquence qui reçoit le signal de sortie du VCO et qui fournit un signal de sortie lequel est divisé en fréquence en fonction du signal de sortie du VCO. Le synthétiseur comprend un trajet de sortie (250, 251) qui comporte un diviseur de fréquence (241). Le synthétiseur émet en outre un signal de sortie dans une fréquence de sortie (FVCO/Nx) du diviseur de fréquence. De plus, le synthétiseur peut avantageusement comporter un circuit intégré qui renferme au moins une partie du VCO. Par ailleurs, l'invention concerne un émetteur ou un récepteur RF, devant par exemple servir dans une station de base d'un système de communications mobiles, qui comprend le synthétiseur.
