Abstract

L'invention concerne un appareil de transmission sans fil que l'on peut appliquer à deux systèmes de communications dont les procédés de communications sont différents l'un de l'autre, qui est petit de taille et d'une efficacité de puissance élevée. L'appareil de transmission sans fil (100) comporte des commutateurs de sortie d'amplificateurs (107a, 107b), un combinateur (108) et un commutateur d'entrée d'antennes (109) entre les amplificateurs (106a, 106b), et les antennes (110a, 110b). Lors de la transmission d'un signal du premier système de communication dont la puissance de transmission maximale est élevée, les amplificateurs (106a, 106b) fonctionnent comme amplificateur non linéaire, les sorties des amplificateurs correspondants sont combinés par le combinateur (108), et les amplificateurs sont exploités comme un amplificateur d'un système LINC qui n'utilise qu'une antenne (110a) pour la transmission. Lors de la transmission d'un signal du second système de communications dont la puissance de transmission est failbe, les amplificateurs (106a, 106b) fonctionnent comme amplificateur linéaire et la transmission MIMO est effectuée au moyen de deux antennes (110a, 110b).
