Low Noise Amplifier Design

This document shows how to use Circuit Design in the Ansys Electronics Desktop to design a small signal 900 MHz low noise amplifier using an S-parameter model of NEC BJT NE68133, including noise parameters. The document also shows how to synthesize matching networks using the built-in Smith Tool. Tuned circuits are connected to the input and output to provide matching, essential to finalizing the design of the low noise amplifier.
