Abstract
A payload includes one or more antennas for receiving polarized radiofrequency signals; a device for regenerating radiofrequency signals by filtering, frequency transposition, and amplification; and antennas for transmitting the regenerated radiofrequency signals to one or more terrestrial terminals. The radiofrequency signal regeneration device includes a plurality of regeneration channels, each channel consisting of an amplification device capable of amplifying two radiofrequency signals having separate frequency bands and the transmission antennas associated with a regeneration chain are capable of transmitting two regenerated radiofrequency signals having orthogonal polarization directions and intended for cells belonging to a single cell layout that uses at least two separate frequency bands and two separate polarizations.
