Radio frequency power amplifiers play a key role in transceivers for mobile communications and their linearity is a crucial aspect. In order to meet the linearity requirements dictated by the standard at a reasonable efficiency, the usage of a linearization technique is desired. For effective implementation of any linearization technique, accurate modelling of power amplifier is required. Due to its less complexity, memory polynomial has been widely used for modelling non-linear system with memory. So in this paper, memory polynomial has been used to model the wideband power amplifier.
