Design Parameters

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, lower height = upper height = 5mm, track width 2.4mm, track gap 0.1mm and track thickness 0.3mm ( approx 10oz copper).

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