| 摘要 |
The invention relates to a payload power amplification device for a multibeam data broadcasting satellite, in which each power amplification block (7, 8) exhibits a plurality of outputs linked to a plurality of broadcasting antennas (4, 5), each output (11, 12, 13, 14) being linked to one and only one broadcasting antenna (4, 5), and at least two switches adapted for being able to selectively link, independently of one another, various subsets of said individual amplifying circuits to any one of said broadcasting antennas (4, 5). The invention extends to a satellite equipped with such an amplifying device. |
