Design and development of low noise amplifier using nonlinear model of transistor for x band applications

Abstract

The demand for wireless network access is dramatically increasing due to the automation of all appliances. The need for high performance wireless transceivers is also warrants more. The successful operation of various electronic gadgets under strong electromagnetic environment is a challenging. The Electro Magnetic Interference (EMI) disturbance is not that much sensitive in consumer electronics. But it has strong influence in the military electronic equipments. Radar, Satellites, commercial communication equipments and other warfare machines need accurate tracking and faithful operation even at the worst natural and manmade environmental pollutions. X band is used for the applications such as satellite communications, radar and Space communications. These applications require an input matched high gain and Low Noise Amplifier (LNA) as a front-end component in their receiver chains. LNA almost suppress the external noise signals entering into the receiver and boosts the wanted signal level. In this project an input matched. newline
