I am a PCB Designer and this is the first time that I am writing to you. =
I am very sorry if you have already answered this question.

I would like to know how to calculate somes impedance between two traces =
if I don't have a plane on the board. One layer is enough to route this =
project.

The impedance between the two traces should be 100 ohms and I do not =
have any ground on the board or from the cable.

So, what can I do to have this impedance? Can I do this with a one =
layer board? Two layer board?=20

Michel.
