Suppose we wish to make a series reflection-free
connection of adaptors
and
using a new three-port series adaptor
, as shown in
Fig.F.9. We make the top port of adaptor
reflection free by
matching its wave impedance
to the series
combination of all other connected adaptors, i.e.,
in
this case. We mark the top port of
as being reflection-free using
the `
' symbol.
