![]() ![]() Network terminations can be input using lumped components networks, complex impedances, and S-parameter files. ![]() To access the Network Terminations dialog box, select Define Source/Load Network Terminations in the Smith Chart Utility window. ![]() The source and load terminations can be defined as equivalent circuits. Snaps to circles of constant reflection coefficient magnitude. Twelve components are available to be used on the Smith Chart for matching purposes. Selecting Circles > Options in the Smith Chart utility window opens the dialog box.Ĭircle colors can be changed on the Smith Chart by choosing Circles > Colors in the Smith Chart utility window. The actual circles plotted are controlled using the bottom portion of the dialog. Using the check boxes at the top of the dialog, these circles can be toggled on and off. The Smith Chart itself consists of four sets of circles of constant value: resistance (R), reactance (X), conductance (G), and susceptance (B). Changes made in the Smith Chart Utility affect the selected SmartComponent. To view a SmartComponent, select the SmartComponent from the SmartComponent drop-down list box in the upper right corner of the utility window. Complex impedance matching is also done in this area by using any of the available passive elements. Noise circles can also be plotted in a similar manner. Gain, VSWR, Q, and Stability circles can be plotted easily by simply entering S-parameters and then choosing the corresponding menu items. In this area the full functionality of a Smith Chart can be utilized.
