Creating a Pad Port

Creating a Pad Port

1. Select the signal layer on which the pad port lies.

2. On the Edit menu, click Select Edges.

3. Click the edges of the model on which the port lies.

The edges do not need to be collinear.

4. On the Draw menu, click Port > Create.

The new pad port is listed under Excitations in the project tree.

Designer will calculate a characteristic impedance of 50 ohms for the pad port. The propagation constant is set to the propagation constant in Teflon, in order to agree with the propagation constant of coaxial probe ports.

To edit the pad port’s properties, double-click the pad port in the project tree. The Edge Port Definition dialog box appears, in which you can perform the following functions:

• Change the pad port’s name.

• Vary the current excitation.

• Renormalize the pad port to a specific port impedance.

Note

Designer automatically defines all ports that connect N-ports to primitive objects as pad ports.
