A reference load is required for calculation of the Quarter wave coupler characteristics (defaults to 50 Ohms).

For your 3db coupler you could start from: Er = 2.2, height = 10mm, track width 4.4mm, track gap 1mm and track thickness 2oz.

However if you are looking for an broadside coupler on a real substrate, then choose a substrate from the catalog.
