Frank,

Try Polar Instruments web site. They have a downloadable demo for impedance calculations.

The copy I am evaluating seems to work pretty good.

Not sure of their address but a search should locate it for you.

     Does anyone have a impedance formula for "Edge coupled surface microstrip"?

Any help would be appriciated.
