Abstract
(EN) The present invention limits deterioration of isolation when performing transmission of both a first transmission signal and a second transmission signal by simultaneous communication. A high-frequency module (1) is provided with a first transformer (120) and a second transformer (220). The first transformer (120) is included in a first differential power amplifier (13) for amplifying a first transmission signal. The second transformer (220) is included in a second differential power amplifier (15) for amplifying a second transmission signal which is communicated simultaneously with the first transmission signal. The direction of a magnetic flux generated in the first transformer (120) and the direction of a magnetic flux generated in the second transformer (220) are different from each other.
(FR) La présente invention limite la détérioration de l'isolation lors de la réalisation d'une transmission à la fois d'un premier signal de transmission et d'un second signal de transmission par une communication simultanée. Un module haute fréquence (1) est pourvu d'un premier transformateur (120) et d'un second transformateur (220). Le premier transformateur (120) est inclus dans un premier amplificateur de puissance différentielle (13) pour amplifier un premier signal de transmission. Le second transformateur (220) est inclus dans un second amplificateur de puissance différentielle (15) pour amplifier un second signal de transmission qui est en communication simultanée avec le premier signal de transmission. La direction d'un flux magnétique généré dans le premier transformateur (120) et la direction d'un flux magnétique généré dans le second transformateur (220) sont différentes l'une de l'autre.
