Patent ID: 8922296

Claim:
An amplification device with reduced bulk comprising at least one plate parallel to a plane XY; and at least two amplifier modules mounted on the plate, each amplifier module comprising, in order of connection, an input connection waveguide, an input transition, an amplifier element, an output transition, and an output connection waveguide, wherein the input connection waveguide and the output connection waveguide are oriented in the same direction X corresponding to a direction of longitudinal propagation, and the amplifier element has an input and output axis oriented in a direction Y perpendicular to the direction of propagation X; wherein the input connection waveguides of the amplifier modules are distinct, have different lengths, and are mounted in parallel to one another; the output connection waveguides of the amplifier modules are distinct, have different lengths, and are mounted in parallel to one another; the sum of the lengths of the input and output waveguides of one and the same amplifier module is identical for each amplifier module; the amplifier modules are mounted in parallel in at least one row; the input waveguides of the amplifier elements of the row are preceded by a power divider; and the output waveguides of the amplifier elements of the row being linked to an output power combiner so that the signals transmitted by the output connection waveguides to the power combiner are in phase, wherein the input divider and/or the output combiner comprises at least one resistive septum which extends walls separating the connection waveguides.
