The number of high power amplifiers required for multi-channel satellite communications is reduced by a high power amplification of selected sets of signals in respec- tive common amplifiers, with each set of combined signals consisting of channels whose frequency bands are mutually discrete and sufficiently separated in frequency that their third order intermodulation products do not substantially overlap in frequency with any of the channels in the same set. The signals can be separated out again after amplification and transmitted as downlink signals, either individually from a dedicated downlink antenna or in combination with other channels in a common downlink antenna.
