Smith Chart Network Area

The Smith Chart Network Area is a quick and easy reference for viewing your matching network and seeing its performance with the given data. A real-time frequency response is plotted for each change made on the Smith Chart. A network schematic is displayed, showing a preview before the SmartComponent is built.

Network Response

The Network Response (frequency response) area can plot both the magnitude and phase of the S-parameters of the drawn network from the Smith Chart.

• Start Freq. Starting frequency point (in Hz) from the left edge of the graph. Default is 0 Hz.
• Stop Freq. Stopping frequency point (in Hz) at the right edge of the graph. Default is twice the Smith Chart frequency.
• Max. Maximum value at the top edge of the graph. Default is 1 for magnitude response and 180 for phase response.
• Min. Minimum value at bottom edge of the graph. Default is 0 for magnitude response and -180 for phase response.
• Type. Chooses plot type, either magnitude or phase.
• Trace1. Chooses which S-parameter to plot in blue.
• Trace2. Chooses which S-parameter to plot in red.
• Reset. Resets the graph to default values.
  The view in the frequency response can be changed by either replacing the edge values with values you want or by clicking and dragging a box inside the graph area.

Network Schematic

The Network Schematic area displays a preview of what the SmartComponent looks like after building the circuit. Also, in this area component parameter values can be changed or components can be deleted from the network.

• Delete Selected Component. Deletes the selected component from the schematic and removes its corresponding trail from the Smith Chart area.
• Set Defaults. Choose default values for Q, loss, and characteristic impedance.
• Zo. The characteristic impedance of the microstrip elements (shorted stub, series stub, and length of line).
• Value. The component's value (e.g., Ohms, Farads, etc.).
• Loss. Displays either a component's loss in dB/m or in Q.
  Any changes made to the schematic area are reflected on the drawing in the Smith Chart area (see Changes in Component Parameters Reflect on Chart).
