Title
(EN) DISTRIBUTED POWER AMPLIFIER CIRCUIT
(FR) CIRCUIT AMPLIFICATEUR DE PUISSANCE DISTRIBUÉ
Abstract
(EN) A distributed power amplifier circuit comprises an amplifier arrangement (100) comprising a plurality of sub amplifiers (110.1 - 110_N), each having an output port (120_1 - 120_N) for outputting an output signal of the sub-amplifier (110_1 - 110_N) and an output combiner network (200) for combining the output signals from the sub amplifiers (110_1 - 110_N). The output combiner network (200) comprises, for each sub amplifier (110 _i), an associated auto transformer (210_i) operatively connected to the output port (120_i) of the sub amplifier (110_i) for receiving the output signal of the sub amplifier (110_i). The auto transformers (210_1 - 210_N) each have a first interconnection terminal (240_1 - 240_N) and a second interconnection terminal (230_1 - 230 -N). The auto transformers (210_1 - 210_N) are operatively connected in series via said interconnection terminals (230_1 - 230_N; 240_1 - 240_N).
(FR) Selon l'invention, un circuit amplificateur de puissance distribué comprend un agencement amplificateur (100) comprenant une pluralité de sous- amplificateurs (110.1 - 110_N), chacun ayant un port de sortie (120_1 - 120_N) permettant de fournir en sortie un signal de sortie du sous-amplificateur (110_1 - 110_N) et un réseau combinateur de sortie (200) permettant de combiner les signaux de sortie provenant des sous-amplificateurs (110_1 - 110_N). Le réseau combinateur de sortie (200) comprend, pour chaque sous-amplificateur (110 _i), un autotransformateur associé (210_i) connecté fonctionnellement au port de sortie (120_i) du sous-amplificateur (110_i) afin de recevoir le signal de sortie du sous-amplificateur (110_i). Les autotransformateurs (210_1 - 210_N) ont chacun une première borne d'interconnexion (240_1 - 240_N) et une deuxième borne d'interconnexion (230_1 - 230_N). Les autotransformateurs (210_1 - 210_N) sont connectés fonctionnellement en série par lesdites bornes d'interconnexion (230_1 - 230_N; 240_1 - 240_N).
