   With this kind of bandwidth, may I suggest it won't be
perfectly flat, so a computer needs to used to normalize
the output by correcting it's actual response.

   I have seen designs for HF directional couplers made
with two (or more) torrid transformers, but directionality
and band width were not reviled.
