Abstract

L'invention concerne un circuit (300) à coupleur actif comprenant un premier module (302) d'amplification avec un certain nombre de premiers ports d'entrée et de premiers ports de sortie. Le premier module d'amplification est configuré pour la préamplification d'un signal d'entrée reçu (entrée RF) et pour générer à partir du signal d'entrée amplifié un certain nombre de signaux de sortie, chacun correspondant sensiblement au signal d'entrée (entrée RF). L'invention concerne également un premier dispositif (304) de commande de gain possédant un certain nombre de ports d'entrée de gain respectivement couplés aux premiers ports de sortie et un port de sortie de gain couplé à au moins un des premiers ports d'entrée. Le premier dispositif de commande de gain est configuré pour commander un gain du premier module d'amplification. De plus, un certain nombre de seconds modules (308, 310, 312) d'amplification correspondant au nombre de signaux de sortie possèdent un certain nombre de seconds ports d'entrée respectivement couplés aux premiers ports de sortie. Chaque second module d'amplification (308, 310, 312) est configuré pour recevoir un signal de commande du second dispositif de commande de gain.
