Abstract
(EN) The invention provides a mixer comprising a multiplier circuit (10) having a first and a second mixer, a generator (30) for generating two first (21, 22) and two second (23, 24) control signals for controlling the first and second mixers, wherein the first and second control signals are in each balanced signals and the first control signals (21, 22) have a frequency f1 and the second control signals (23, 24) have a different frequency f2.
(FR) L'invention concerne un mélangeur comprenant un circuit multiplicateur (10) comportant un premier et un deuxième mélangeurs, un générateur (30) pour générer deux premiers signaux de commande (21 ; 22) et deux deuxièmes signaux de commande (23, 24) pour commander les premier et deuxième mélangeurs. Les premier et deuxième signaux de commande sont, dans chaque cas, des signaux équilibrés et les premiers signaux de commande (21 ; 22) présentent une fréquence f1 et les deuxième signaux de commande (23, 24) présentent une fréquence différente f2.
