Abstract

Low noise amplifiers (LNAs) are one of the basic building blocks of any communication system. The purpose of the LNA is to amplify the received signal to acceptable levels with minimum self-generated additional noise. Gain, NF, non-linearity and impedance matching are four most important parameters in LNA design. In this paper, we present the design details and simulation results of low-noise amplifier at S band.
