Abstract
A new model is presented in order to simulate the non-linear behavior of solid state power amplifiers. This model is based on static, together with dynamic measurements. The model has been validated through the use of the COSSAP system simulator. A good agreement has been found between measured and calculated curves, such as noise power ratio (npr) and bit error rate (BER)curves.
Résumé
Un nouveau modèle est présenté pour simuler le comportement des non-linéarités des amplificateurs de puissance à état solide. Ce modèle est caractérisé non seulement par les mesures statiques mais aussi par les mesures dynamiques. Étant installé sur le simulateur système COSSAP, ce modèle a été validé par comparaison avec les courbes expérimentales : la courbe du rapport de puissance de bruit et la courbe du taux d’erreurs binaires (teb).
