What Is RF Tool?

RF Tool is a GUI that provides a visual interface for creating and analyzing RF components and networks. You can use RF Tool as a convenient alternative to the command-line RF circuit design and analysis objects and methods that come with RF Toolbox software.

RF Tool provides the ability to

• Create and import circuits.

• Set circuit parameters.

• Analyze circuits.

• Display circuit S-parameters in tabular form and on X-Y plots, polar plots, and Smith Charts.

• Export circuit data to the MATLAB workspace and to data files.

Opening RF Tool

To open RF Tool, type the following at the MATLAB prompt:

rftool

For a description of the RF Tool GUI, see RF Tool Window. To learn how to create and import circuits, see Creating and Importing Circuits.

Note   The work you do with this tool is organized into sessions. Each session is a collection of independent RF circuits, which can be RF components or RF networks. You can save sessions and then load them for later use. For more information, see Working with Sessions.

RF Tool Window

The RF Tool window consists of the following three panes:

• RF Component List

  Shows the components and networks in the session. The top-level node is the session.

• Component Parameters

  Displays options and settings pertaining to the node you selected in the RF Component List pane.

• Analysis

  Displays options and settings pertaining to the circuit analysis and results display. After you analyze the circuit, this pane displays the analysis results and provides an interface for you to view the S-parameter data and modify the displayed plots.

The following figure shows the RF Tool window.

RF Tool Workflow

When you analyze a circuit using the RF Tool GUI, your workflow might include the following tasks:

1. Build the circuit by

   • Creating RF components and networks.

   • Importing components and networks from the MATLAB workspace or from a data file.

   See Creating and Importing Circuits.

2. Specify component data.

   See Modifying Component Data.

3. Analyze the circuit.

   See Analyzing Circuits.

4. Export the circuit to the MATLAB workspace or to a file.

   See Exporting RF Objects.
