I have put 2 lumped ports, one for input, one for output. Changing the impedance of my output port impedance for example to 100 Ohms or 150 Ohms changes my Z-parameters, but shouldn&#8217;t Z-parameters be independent of those impedances? if not, how is that impedance shown in an equivalent circuit?
