Abstract

L'invention concerne un modulateur à inversion de polarité. Dans ce modulateur comportant quatre transistors Tr1... Tr4, un courant identique est injecté dans le conducteur commun d'alimentation des émetteurs de chaque couple de transistors Tr1, Tr2; Tr3, Tr4; les collecteurs des quatre transistors sont raccordés par l'intermédiaire d'un montage croisé à un système de production de courant en rapport géométrique, formé par deux transistors Tr5, Tr6, le signal d'entrée étant injecté dans l'un des deux conducteurs et le signal de sortie étant prélevé du côté collecteur en amont du système Tr5, Tr6. Application notamment dans les convertisseurs de canaux pour la technique des fréquences porteuses.
