  • Abstract
    This paper presents a technique to linearize the high power amplifier (HPA) through a predistorter (PD). The characteristics of the PD circuit are derived based on the extension of Saleh´s model for HPA and a simple linear-log model. Numerical results are shown for Global Broadcasting Service (GBS) applications.
