Abstract
(EN)
An amplifier module (600) with an output coupler (640) is disclosed. The amplifier module (600) may include a plurality of input terminals (601-605) and two or more output terminals (610, 611). Each input terminal may be coupled to an input of an independent amplifier (620-624). Outputs from the independent amplifiers (620-624) may be coupled to the two or more output terminals (610, 611). The amplifier module (600) may include an output coupler (640) to couple the two or more output terminals (610, 611) together. A signal may be received by a first output terminal (610) and be coupled by the output coupler (640) to a second output terminal (611). In some embodiments, when the two or more output terminals (610, 611) are coupled together, the independent amplifiers (620-624) may be made inactive or operated in a minimum gain configuration.

Cette invention concerne un module amplificateur (600) avec un coupleur de sortie (640). Selon un mode de réalisation, ledit module amplificateur (600) comprend une pluralité de bornes d'entrée (601-605) et deux ou plusieurs bornes de sortie (610, 611). Chaque borne d'entrée peut être couplée à une entrée d'un amplificateur indépendant (620-624). Les sorties des amplificateurs indépendants (620-624) peuvent être couplées aux deux ou plusieurs bornes de sortie (610, 611). Le module amplificateur (600) peut comprendre un coupleur de sortie (640) pour coupler mutuellement les deux ou plusieurs bornes de sortie (610, 611). Un signal peut être reçu par une première borne de sortie (610) et être couplé par le coupleur de sortie (640) à une seconde borne de sortie (611). Selon certains modes de réalisation, lorsque les deux ou plusieurs bornes de sortie (610, 611) sont couplées l'une à l'autre, les amplificateurs indépendants (620-624) peuvent être rendus inactifs ou commandés selon une configuration de gain minimum.
