Cecil, have forgotten that because the source resistance of the RF
power amp is non-dissipative, none of the reflected power is absorbed
therein?
Actually, this discussion is based on an example introduced by W7EL
which assumed a 50 ohm source resistor in his "food for thought,
forward and reflected power" article posted on his web page. The
source resistance of an actual RF power amp doesn't matter. W7EL's
example specified a 50 ohm resistor as the source impedance.
