Design of a wide band low noise amplifier

Abstract

The article you are about to read holds the proposition of a wideband low noise amplifier operating in the microwave frequency band starting from 0.5GHz ending at 5GHz, the article includes all steps of LNA design from DC biasing, to wideband matching. It also includes simulation results of each step of the design process. The introduced LNA is a two stage device, the first stage is a pre-amplifier with a low noise figure, the second one is a high gain amplifier, that is to reach a topology with a high gain and low noise figure across the whole operating band simultaneously. The simulation results are then compared to datasheets of LNA devices to decide the performance level of the proposed device.
