Experts,
I have been searching for a hand calculation of cutoff frequency
for a coaxial contact. I have been able to find many for coaxial cable. However,
I do not know the assumptions that are being made to derive these equations.
Cutoff Frequency = 7.5/SQRT(er)(D+d)
or
Cutoff Frequency= ((2*c)/(PI*sqrt(er)))*1/(D+d)
D = Sheild inner diameter
d = Conductor outer diameter
Any insight?
Thanks,
Merrick
