    I would like to have 60 ohm impedance controlled lines, but I don't want to shell out for a multilayer PCB. Could I just use a double sided PCB and use one side of it as a ground plane?

    Would board thickness be an issue? I know that having a thicker board will adversely effect the coefficient of coupling.

    The 60ohm impedance does not have to be precise, it could vary as much as 20ohms or perhaps more. The most important thing is that it doesn't have any major reflections. I will use widely available equations to calculate the trace width.

    on ordinary double sided 1/32 fiberglass, 1/10 inch width gives you 50 ohms. use the other side as a ground plane, and miter your turns. source, various ham radio microwave books and the ITT Handbook for radio engineers.
