Title: A Design, Analysis and Optimization Technique of 1.9 GHz CDMA Low Noise Amplifier
Authors: Mehdi Rahnama and Alishir MoradiKordalivand
Abstract: In this paper, a 1.9 GHz CDMA low noise amplifier (LNA) has been designed, analyzed and simulated using GaAs technology with high RF performances. A technique to design this LNA is presented along. The proposed low noise amplifier allows a receiver system to become adaptive to an antenna’s array, waveguides and a transmission lines, as well as standard antenna signal powers. It is also suitable for applications in cellular and PCS handsets, and other systems requiring super low noise figure with good intercept in the 0 to 10 GHz frequency range. At 1.9 GHz, the amplifier is optimized to provide a power gain of 15 dB, a noise figure (NF) of only .95 dB. The proposed LNA dissipates a power of 20 mW at a supply voltage of 2V. Although this paper is based on LNA design with a specific transistor, this general LNA design technique can be used for other transistors and applications
