A new linearisation technique for an RF high-power amplifier (HPA) using a post-distortion error canceller (PDEC) is presented. The PDEC generates an error signal based on the complex envelope transfer characteristics of the HPA, which is combined at the output of the HPA. Therefore, the stability of the system is guaranteed
