I have to agree with a lot of what's been said. Especially that there are
usually more things happening than can be modeled by a simple "Zo" number.

One cute solution is the slide rule-style calculator from National
Semiconductor. It's given out for free (can't beat the price) as the
"Transmission Line Rapidesigner". There are both English and Metric versions and
they are described fully in Application Note 905 (AN-905).

I also use various 2D simulators to get the full RLCG matrices when needed. My
favorites here are the Artech House DOS program "LINPAR" (Harrington, et. al.)
and COSMOS/M which is a full 2D/3D finite element simulator.

Do what works for you, I say. All Best, Jack Marshall.......
