S-Parameters and Linear Components

Touchstone files, S-parameter simulation, lumped and distributed elements

You can specify linear networks by importing S-parameter data files directly into RF Blockset™ models. To plot S-parameter data and the results of rational fitting, use the S-Parameters block. Other RF Blockset blocks enable you to build models using passive components like resistors, capacitors, inductors, and transmission lines.
