Abstract
A predistortion linearization device (D) produces gain and phase expansions making it possible to compensate for the gain compression and phase variation of a power amplifier. This device (D) also allows the conventional adjustment of amplitude, the adjustment of the form of the gain and phase expansions as a function of a microwave input signal (Se).
