Abstract: A distributed amplification device with p inputs, p outputs, p amplification paths comprises a redundant reservoir of n amplifiers including n-p back-up amplifiers, an input redundancy ring and an output redundancy ring formed by rotary switches, the input and output redundancy rings sharing the same technology. The internal amplification pathways associated with the n-p back-up amplifiers frame in an interlaced manner the internal amplification pathways associated with the p nominal amplifiers and the amplification paths of the routing configurations each pass through at least five rotary switches. The input and output redundancy rings are topologically and geometrically configured and the family of the routing configurations is chosen such that the electrical lengths of all the paths of one and the same routing configuration of the family are equal.

Abstract: A method is provided which includes: defining at least one radiofrequency performance objective to be produced on a selected coverage area on the ground; producing a rigid shell having a predefined profile; producing a reflecting flexible membrane; determining, by successive iterations, N optimum local deformations to be applied at N different points of the flexible membrane; producing N rigid supporting bars of different lengths corresponding to the optimum local deformations to be applied to the flexible membrane; and positioning and rigidly fixing the flexible membrane onto the rigid shell via the N supporting bars.
