RF Toolbox 2.7

Designing Networks

RF Toolbox helps you build complex RF networks from simpler components in a visual environment. Using the RF Toolbox, you connect components in series, parallel, cascade, hybrid, and inverse hybrid configurations by calling the appropriate toolbox function with the components as arguments. The return value is a new object that represents the configuration's behavior. This object can be passed in turn as an argument to other toolbox functions.

In addition to calculating the small signal frequency response, RF Toolbox calculates input and output reflection coefficients, stability factors, noise figures, and third-order intercept points for cascaded components. It also enables you to de-embed S-parameters from cascaded networks.
