New satellites generations have regenerative payload. Received signals are demodulated in order to be processed, before being modulated again andamplified on-board. For correcting non-linearities due to High Power Amplifier (HPA) operating near saturation, a predistortion system based on Neural Networks (NNs) was developed. For size, consumption and bandwidth purposes, the Multi-Layer Perceptron (MLP) type NNs were implemented in a 0.6 ?m CMOSASIC. This paper presents the linearization ability of the analog integrated NN to correct the AM/AM distortion due to the HPA for changing simulation conditions (temperature drifts, ageing variations).
