Abstract:In this paper; the performances of various bias classes of Power Amplifiers (PA) working in 802.11a transmitters are presented. Computer simulations of a complete 802.11a transmitter have been made in order to investigate the PA efficiency and Adjacent Channel Power Ratio (ACPR) at the output of the non-linear PA. A high-level power amplifier model is used to model the different classes of amplifiers (class A; class B; class AB and class C) according to the conduction angle at the output signal of the PA. Other behaviors given in real amplifiers; such as the saturation level and compression near saturation are modeled as well. Results of PA efficiency; ACPR and output spectra are presented.
