You mean 3 mini coax connectors inside a DB style shell? Those are pretty
widely used. Sun used them. That style of design is still in use, you should
have no trouble finding them in good electronic parts catalogs.
For example, I went to digikey.com and asked it for "3w3", it came up with lots
of matches with a number of different pin configurations --
It looks like "3W3" means 3 large holes in the shell, but not necessarily coax
-- a lot of them seem to be high power pins instead. Mouser may be using "C"
instead of "W" to mean coax.
Here's a nice reference:
-- the "complete combination d-sub connectors" PDF download at the bottom
right has lots of detail about many different combinations. You'll want to be
careful to match the exact connector style you need.
It looks like coax pins are often crimp style, but solder style also are
mentioned in the conec catalog. I suspect solder style is harder to find --
crimp is the normal style in volume production work.
