Consider the impedance matching network shown at left below, where a load ZL (L ) at port 2 is matched to a source impedance Z0 at port 1. Show that the same network will present the impedance Z = Z∗ L at port 2 when port 1 is terminated with Z0, as shown in the figure below at right. Assume the matching network is reciprocal and lossless. This relationship allows the impedance tuning techniques of Chapter 5 to be used to design the input and output matching networks for an amplifier.
