Hi,

Can someone tell me where the theory reference is for the following eqn.

Its located in "Network analysis applying the 8510TRL calibration for non-coaxial measurements"

Electrical length(cm)=15/(f1(GHZ)+f2(GHz))

THanks in advance

It is in a similar format as the normal L[cm]=30/f[GHz] formula, but now we have the average of two values and L/4 desire.

Don't forget that this is electrical length, not physical. Compensate for waveguide effects, or Er, or whatever your media requires.

Dr. Joel has further comment in another thread you can search out.

Best wishes.
