Abstract

Dispositif de conversion de fréquence qui décale en fréquence un signal de bande de base conformément à un signal de local pour émission. Le dispositif de conversion de fréquence comprend: un mélangeur qui multiplie le signal de bande de base par le signal local pour émission; un multiplexeur qui reçoit le signal de bande de base par un premier port, transmet le signal de bande de base reçu par un deuxième port en direction du mélangeur, et émet une composante de fuite provenant du mélangeur vers le deuxième port, ceci à partir d'un troisième port différent du premier port, sans passer par le premier port; et une unité de fourniture de signal de bande de base qui fournit le signal de bande de base au premier port du démultiplexeur. Le démultiplexeur possède: un filtre passe-bas disposé entre le premier et le deuxième port, laissant passer une composante de fréquence du signal de bande de base, mais pas une composante de fréquence du signal local; et un filtre passe-haut disposé entre le troisième et le deuxième port, laissant passer une composante de fréquence du signal local, mais pas une composante de fréquence du signal de bande de base.
