RF Network Construction

Networks of circuit objects, ladder filters, transmission lines

Use these RF Toolbox™ classes and functions to define RF network components and connect them in series, parallel, cascade, hybrid, and inverse hybrid configurations. Then you can use these networks to perform additional RF analysis.

Alternatively, use classes such as capacitor , inductor, and resistor to create arbitrary networks and calculate the S-parameters and group delay.
