Design and Analysis of Broadband Matching Networks for a Low Noise Amplifier

Designing Broadband matching networks is an important part of RF amplifier design. Reflection factors and the placement of a LNA in each matching network at a specified frequency place an important role for designing the Broadband matching network. In this paper the author discussed about the procedure for designing a LNA over a specified bandwidth by lumped LC elements and analyse the performance like target gain and noise figure using RFTOOL box. A direct search based approach is used to arrive at the optimum element values in the input and output matching network
