A Novel Design of Low-Noise RF Amplifier for Orthogonal Frequency Division Multiplexing

Communication plays very important role in day-to-day life of people. Due to fast growing age, multi carrier communication is preferred over single carrier waves for better transmission. One of the advantages of OFDM system over the single carrier system is the better performance in multipath environment. For narrowband operation, one may construct simple ampli?ers whose noise ?gure and power gain are close to the theoretical optima allowed within an explicit power constraint.This paper introduces the design of a 1.5 GHz Low-Noise amplifier using Agilent ADS software. The proposed design aims to provide a better gain of 12.7 dB with low Noise Figure (NF) of 1.76 dB.
