| 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. |
