Renormalizing S-Matrices

To renormalize an S-matrix to a specific port impedance:

1. From the Project Manager window, expand the Project Tree and [Active Design Folder] > Excitations.
2. Double-click an appropriate edge port to open the Edge Port Definition window.

   

3. Ensure Post Process Port is selected (default).
4. Select Renormalize Impedence and set the amount to a non-zero value. The default impedance for re-normalization of each port is 50 ohms.

• If the impedance is a complex quantity, type the real part of the impedance to the left of a plus sign (+) and the imaginary part of the impedance followed by i to the right of the plus sign (e.g., enter 50 + 10i).

4. Enter the length of the transmission line to be added in the Deembed Distance field.
5. Click OK to renormalize the port to the new impedance.

You do not need to re-run a simulation in order to renormalize a port. The 2D Reporter automatically updates its reports to reflect the renormalized S-matrix.
