electrical length of what? If it is well matched
and well behaved, like a transmission line, you
can figure out the group delay passing thru it by
looking at angle[s21].
Td=delta phase/delta
frequency
ang[s21] at 1 ghz = -20 degrees
angl[s21] at 1.1 ghz = -25 degrees
Td=(25-20)/((360
deg/cycle)*100MHz) = 138 pS electrical length
