I'm working on a project on calibration,
i would like to find out whether my results are logical or not.
are the following statements true?
S11 = reflection coefficient
S21 = transmission coefficient
-20log10 (S11) = return loss
-20log10 (S21) = insertion loss
now how is the return loss related to insertion loss?
or how is the reflection coefficient relates to the transmission coefficient?
i've read this thread,
https://www.edaboard.com/threads/162644/
one member says that
Transmission coefficient = 1 - ΓL
but in RF circuit design text book page 85,
equation 2.86 says that
To = 1 + Γo
so...i'm thoroughly confused.
please help me.
thanks
