The invention relates to an amplifier device with reduced bulk comprising at least one plate parallel to a plane XY and at least two amplifier modules (41a, 41b) mounted on the plate, each amplifier module (41a, 41b) comprising an amplifier element (11a, 11b), an input connection waveguide (12a, 12b) and an output connection waveguide (13a, 13b) positioned in the same direction X corresponding to a direction of longitudinal propagation, the amplifier element (11a, 11b) having an input and output pin (18a, 18b) positioned in a direction Y perpendicular to the direction of propagation X, characterised in that the input connection guides (12a, 12b) of the two amplifier modules (41a, 41b) are different, have different lengths (La1, La2) and are mounted parallel to one another, the output connection guides (13a, 13b) of the two amplifier modules (41a, 41b) are different, have different lengths (La2, Lb2) and are mounted parallel to one another, and in that the sum of the lengths (La1 + La2, Lb1 + Lb2) of the input and output guides of the same amplifier module is identical for each amplifier module: La1 + La2 = Lb1 + Lb2.

Le dispositif d'amplification à encombrement réduit comportant au moins un plateau parallèle à un plan XY et au moins deux modules amplificateurs (41a, 41b) montés sur le plateau, chaque module amplificateur (41a, 41b) comportant un élément amplificateur (11a, 11b), un guide d'ondes de connexion d'entrée (12a, 12b) et un guide d'ondes de connexion de sortie (13a, 13b) orientés selon une même direction X correspondant à une direction de propagation longitudinale, l'élément amplificateur (11a, 11b) ayant un axe d'entrée et de sortie (18a, 18b) orienté selon une direction Y perpendiculaire à la direction de propagation Xt caractérisé en ce que les guides de connexion d'entrée (12a, 12b) des deux modules amplificateurs (41a, 41b) sont distincts, ont des longueurs (La1, La2) différentes et sont montés parallèlement l'un par rapport à l'autre, les guides de connexion de sortie (13a, 13b) des deux modules amplificateurs (41a, 41b) sont distincts, ont des longueurs (La2, Lb2) différentes et sont montés parallèlement l'un par rapport à l'autre, et en ce que la somme des longueurs (La1+La2, Lb1 +Lb2) des guides d'entrée et de sortie d'un même module amplificateur est identique pour chaque module amplificateur : La1 +La2 = Lb1 +Lb2.
