Linearity of an RF amplifier (100) is enhanced by a feedforward correction system which utilizes a carrier reutilization synchronous detection system whereby an RF input signal (30) is modulated and utilized, by way of carrier to sideband multiplication, to provide synchronous detection used for system alignment over time, temperature, and input power level.

Dans cette invention, on augmente la linéarité d'un amplificateur RF (100) au moyen d'un système de correction aval utilisant un système de détection synchrone de réutilisation de la porteuse, un signal d'entrée RF (30) étant modulé et utilisé, via une porteuse en vue d'une multiplication à bande latérale, de manière à permettre une détection synchrone utilisée pour l'alignement de système en fonction du temps, de la température, et du niveau de puissance d'entrée.
