Parametric Performance Analysis of 2-GHz Low Noise Amplifier

In this paper designed, implemented and simulated LNA is divided into two parts. In the first part, LNA is based on lumped elements and in second part LNA is based on distributed elements. Two designed methods have been compared and best performance is obtained with lumped elements. The designed amplifier provides a noise figure of 0.358 dB , gain of 16.778 dB, input return loss is -4.917dB and output return loss is -10.045 dB. LNA is simulated at 2 GHz by employing active device like MESFET sp_hp_ATF34143_4_19990129. Parametric performance analysis is carried out using Advanced Design Simulation (ADS) tool of Agilent Technologies. This paper highlights or shows the all necessary steps or different performance parameters for LNA design.
