Tune this value until S11 is at the center of the smith chart or is below -30 dB on the rectangular plot. This variable can be tuned and/or optimized. Now notice that the impedance on each port of the line is set to a variable z which is set equal to 50 ohms. \) to 1 needs to lie on these circles and the intermediate point will be where these circles intersect. To get 75 Ohm s-parameters from 50 Ohm parameters, convert to impedance (for example, by plotting on a Smith Chart normalized to 50 Ohms, or by formula). We are plotting both S11 on a smith chart and a rectangular plot. ![]()
