LINC2’s Smith Chart view of the prototype amplifier simulation results.
The program LINC2 (LINear Circuit Analysis version 2), is a circuit simulation program written for the Microsoft Windows (TM) graphical operating environment. The program uses a nodal circuit file description that is very similar to several of the most popular RF/Microwave simulator programs currently used in the industry today.
