Abstract
Circuit amplificateur comprenant un amplificateur de porteuse (24) produisant un signal de sortie d'amplificateur de porteuse, un amplificateur de correction (26) couplé à l'amplificateur de porteuse (24) dans une configuration de Doherty, et un circuit de combinaison réceptif à l'amplificateur de porteuse (24) et à l'amplificateur de correction (26). L'amplificateur de correction (26) est polarisé en tension pour produire un signal de produit d'intermodulation ajusté. Le circuit de combinaison (35) combine le signal de produit de modulation ajusté avec le signal de sortie de l'amplificateur de porteuse pour produire un signal de sortie de circuit amplificateur sensiblement linéarisé.
