Multi-stage linearizer

Multi-stage linearizer

A high-linearity linearizer system includes a multi-stage linearizer circuit formed by cascading multiple linearizer circuits. The multi-stage linearizer circuit is configured to pre-distort an input signal to generate a pre-distorted signal. A non-linear high-power amplifier (HPA) having non-linear...

description A high-linearity linearizer system includes a multi-stage linearizer circuit formed by cascading multiple linearizer circuits. The multi-stage linearizer circuit is configured to pre-distort an input signal to generate a pre-distorted signal. A non-linear high-power amplifier (HPA) having non-linear characteristics is coupled to the multi-stage linearizer circuit and is configured to amplify the pre-distorted signal. Pre-distortion characteristics of the multi-stage linearizer circuit are configured to counter the non-linear characteristics of the non-linear HPA and to compensate a non-linearity of the non-linear HPA to achieve a desired level of linearity.
