If one was designing a mincrostrip passband filter for a 2-port network, one
would look at s21 and s11 (to see how much signal was being reflected).
However, if one had two filters cascaded with each other, with a trunk line
terminating each filter segment (ie two multiplexer segments) so that the
first segment had a passband at 5.2GHz and the other at 6.3GHz, the circuit
would effectively be a 3-port network.
Which S-parameters would we need to observe in order to see the filter
characteristics?
