Abstract

L’amplificateur comporte au moins : un premier amplificateur push-pull (21) ; un deuxième amplificateur push-pull (22) ; un dispositif d’aiguillage (20) ; un premier coupleur hybride 90° (23), couplé aux entrées desdits amplificateurs (21, 22) ; un deuxième coupleur hybride 90° (24) couplé aux sorties desdits amplificateurs (21, 22), via ledit dispositif d’aiguillage ; ledit dispositif d’aiguillage et lesdits amplificateurs étant contrôlés de telle façon que : lesdits amplificateurs sont balancés par lesdits coupleurs lorsque ledit amplificateur de puissance fonctionne dans une bande de fréquences donnée, la sortie dudit premier amplificateur (21) étant aiguillée vers ledit deuxième coupleur (24) ; le premier amplificateur (21) est actif et le deuxième amplificateur est éteint lorsque ledit amplificateur de puissance fonctionne en dehors de ladite bande de fréquences, la sortie dudit premier amplificateur (21) étant aiguillée directement en sortie (Out 2) dudit amplificateur de puissance.
