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 Orthogonal Frequency Division Multiplexing system over the single carrier system is the better performance in multipath environment. For narrowband operation, one may design an RF power amplifier whose noise figure and optimal gain are close to the theoretical optima allowed within an explicit power constraint.This paper introduces the design of a 1.5 GHz two-stage RF power amplifier using CAD software. The proposed design aims to provide a better gain of 29.1 dB delivering optimal power of 20.53 dBm suitable for wireless communication.

Abstract


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 Orthogonal Frequency Division Multiplexing system over the single carrier system is the better performance in multipath environment. For narrowband operation, one may design an RF power amplifier whose noise figure and optimal gain are close to the theoretical optima allowed within an explicit power constraint.This paper introduces the design of a 1.5 GHz two-stage RF power amplifier using CAD software. The proposed design aims to provide a better gain of 29.1 dB delivering optimal power of 20.53 dBm suitable for wireless communication.
