S-Parameter Calculations
The RF interfaces have built-in support for S-parameter calculations. Use a Port boundary feature for each port in the model. For connecting transmission lines and other lumped feeds, use a lumped port that approximates a connecting transmission lines or a voltage source with a known internal impedance. The lumped port should only be used when the port width is much smaller than the wavelength.

See Port and Lumped Port for instructions to set up a model.
