Positively coupled parallel lines.

The coupled lines are summed monotonically. There are three possiblities, symmetrical, asymmetrical and custom.

Symmetrical Multi-stage Couplers

The tight coupling is in the centre with a monotonic progression to the loose coupling on the exterior.


Asymmetrical Multi-stage Couplers

A progressive coupling from tight to loose along the length of the stages. Different types of progression.


A Custom Multi-stage Couplers

Choose the number of stages. Enter the coupling factor for each stage and see what you get.
