Cecil,

Try it.

I believe you will find that your equality requirement on angles reduces
to precisely the simple equation offer by Reg.

(Zo = Ro) is extremely simple. It is -

G = C * R / L



Wonder why Ramo and Whinnery say that's an approximation for low-loss
lines? If the R+jwL angle is equal to the G+jwC angle, doesn't that
make Z0 purely resistive?
