RF Model Objects

Overview of RF Model Objects

RF Toolbox™ software uses model (rfmodel) objects to represent components and measured data mathematically for computing information such as time-domain response. Each type of model object uses a different mathematical model to represent the component.

RF model objects provide a high-level component representation for use after you perform detailed analysis using RF circuit objects. Use RF model objects to:

  • Compute time-domain figures of merit for RF components

  • Export Verilog-A models of RF components

Available Model Objects

The following table lists the available rfmodel object constructors and describes the model the corresponding objects use. For more information on a particular object, follow the link in the table to the reference page for that object.
