摘要
A nonlinear behavioural model of power amplifiers is proposed with an improved modelling method to fit up to the alternate channels where the noise contributions are dominant. From a memory polynomial model incorporating memory effects (Ku and Kenney 2003), noise contributions are considered for a better modelling. The proposed modelling method is utilised to model power amplifiers for Wideband Code Division Multiple Access (WCDMA) 1700 and 2100 bands. The power amplifier behaviour is modelled within 1dB accuracy up to the alternate channels.
