The System NF Calculator (SysNF) app calculates the noise figure of a cascaded microwave network. The app contains a variety of built-in RF/microwave components including amplifiers, active and passive filters, mixers, transmission lines and more, enabling the user to create highly realistic systems. Components can be added,
deleted, or its parameters modified anywhere along the chain after the first pass, thus giving maximum system design flexibility.
This app was created to help microwave engineers and technicians to get quick and accurate answers in "real-time" while in the lab, the production floor, in design review meetings, or just to test out some ideas with little computational and time overhead.
