That one looks interesting indeed. Especially as the datasheet mentiones
quadrifilar. Now I wonder whether that means the internal structure is
a quadirfilar transformer or it is meant for quadiriflar antennas.
While the latter would be a weird way to describe it, the former sounds
more plausible. But then, I have no idea how one could use a quadrifilar
transformer for a polyphase splitter. Does someone have an idea?
