What is Extracting S-Parameters with SPICE about?
A SPICE circuit analysis can be used to extract scattering parameters (S-parameters). The document describes a circuit with a transistor and constant current sources used to set the emitter and collector voltages. S-parameters are obtained by running an analysis in SPICE, with S11 versus frequency shown for this example. Zooming in on the S11 graph at 50 MHz reveals that S11=0.717 at -60.7 degrees, corresponding to an input impedance of 29.9-j76.9 Ohms.
