Abstract
A radio frequency channel amplification module for communication satellite, comprises an input configured to convey an input radio frequency signal, an output configured to restore a pre-amplified output radio frequency signal intended to power a travelling wave tube amplifier that can be equipped with linearization means with predistortion, at least one first upstream gain control module arranged downstream of the input and one second downstream gain control module arranged downstream of the first upstream gain control module and upstream of any linearization means by predistortion. The channel amplification module also comprises an instantaneous power limiter intended to clip the peaks of the input radio frequency signals with a level exceeding a determined threshold value, the instantaneous power limiter being arranged in series between said first upstream gain control module and said second downstream gain control module.
