Abstract
The present invention relates to an amplification device for a satellite in order to amplify a plurality of n transmission channels to an output corresponding to a beam, the device comprising: frequency band combining means comprising n inputs in order to receive the n transmission channels and q outputs in order to supply respectively the channels grouped together within q frequency bands, a power amplification unit including p active amplifiers in parallel for the distributed amplification of the n channels, gain and phase adjustment means corresponding to the p power amplifiers on the q frequency bands.
Claims2
An amplification device (8) for a satellite in order to amplify a plurality of p transmission channels to an output corresponding to a beam, the device comprising:
- a frequency band combining means (10) comprising n inputs in order to receive the n transmission channels and q outputs in order to supply respectively the channels grouped together within q frequency bands (Band1-Band4),
- a power amplification means (121) including p amplifiers in parallel for the distributed amplification of the n channels,
- a gain and phase adjustment means (113) corresponding to the p power amplifiers on the q frequency bands.
