This topic helps you to determine when to use RF
rfckt objects in your RF analysis
RF Toolbox™ provides two approaches to construct and analyze RF networks:
Networks built using elements based on the RF
Networks built with
To understand when to use RF
rfckt objects, see this table.
|Construct networks with N-ports
|Import N-port S-parameters
|Matching network design
|Yes (N-port in RF
circuit, two-port in
|Yes (Two-port networks only)
|Group delay analysis
rfbudget — Friis and Harmonic Balance methods)
|Yes (Friis method)
|AM-PM definitions of nonlinear amplifier
Yes (since R2023b)
|Compatible with RF Blockset™ Circuit Envelope library blocks (You can import and export
rfbudget objects to Circuit Envelope library).
|Compatible with RF Blockset Equivalent Baseband library blocks.
You can use this table as a reference when designing and analyzing your RF systems. For more on how to design an RF system using these objects, see:
The RF chain shown in both examples is identical and provides the same result on analysis.
