Yep. That's where my interest comes from. I keep seeing directional
couplers on ebay for hundreds of dollars (used) and I know there
is nothing inside but three traces on a board and a few connectors.
I used to work as an R&D tech in a company that made microwave
equipment so I know how to design, tune, and test something like
this. I just don't know how to fab them.
Thanks for the reply Leon.
