High-Efficiency Low Noise Amplifier Design for Enhanced Receiver Sensitivity in S- and C- band Frequencies

C. R. Ravinthiran

Abstract: This research paper focuses on the design and implementation of a Low Noise Amplifier (LNA) with the objective of achieving a gain greater than 28 dB, a noise figure less than 0.4 dB and a receiver sensitivity better than -123 dBm in the S and C band ranges (between 2 GHz to 8 GHz frequency range).The amplifier is intended to operate at a low voltage supply of 1.8V, making it suitable for power-constrained applications. The paper presents a comprehensive analysis of the literature, discusses the methodology employed in the design, presents simulation results using Multisim-14.3 software and testing and experimental results of prototype circuit and concludes with a discussion of the findings and potential future work.

Keywords: Low Noise Amplifier (LNA), Gain, Noise Figure, Receiver Sensitivity, Voltage Supply
