Device for linearizing transmission amplifiers for a transmitter facility comprising a plurality of transmitters (11, 12, ... 1n) each comprising a transmission amplifier (4) and not completely decoupled from one another, the said device comprising means for activating the transmission of linearization signals relative to each amplifier, means (6) for analysing the corresponding amplified linearization signals, to determine the non-linearities of the said amplifier, and to apply to signals deemed useful a pre-correction (5) to compensate for the said non-linearities, and the said device being essentially distinctive in that it comprises centralized control means (8, 8', 10-20) to activate the transmission of linearization signals relative to different transmission amplifiers at different times.

Dispositif de linéarisation d'amplificateurs d'émission pour équipement émetteur comportant une pluralité d'émetteurs (11, 12, ...1n) comportant chacun un amplificateur d'émission (4) et non totalement découplés les uns des autres, ce dispositif comportant des moyens pour commander l'émission de signaux dits de linéarisation relatifs à chaque amplificateur, des moyens (6) pour analyser les signaux de linéarisation amplifiés correspondants, afin de déterminer les non linéarités de cet amplificateur, et d'appliquer à des signaux dits utiles une précorrection (5) destinée à compenser ces non linéarités, et ce dispositif étant essentiellement caractérisé en en ce qu'il comporte des moyens (8, 8', 10-20) dits de commande centralisée pour commander l'émission de signaux de linéarisation relatifs à différents amplificateurs d'émission à des moments différents.
