Does anyone know of a connector that'll pass multiple 8+) RF signals with
specs somewhere in the ballpark of 100kHz-3GHz, isolation between signals at
least 80dB or so? I'm aware of the FCT connectors
(http://www.fctgroup.com/Englisch/prod/ml/default.asp) that Mouser sells, and
this is what I intend to use for "box to box" connectivity, but for PCB to PCB
connectivity within a box, I was hoping to find something a little denser (FCT
gives you 7 coax connectors in a DB-37 sized shell).
Samsung and friends have high speed connectors that typically have a ground
plane 'down the middle' of a two row connector, but the data on their website
seems squarely aimed at digital signals where a couple percent crosstalk is
fine; in my case there can readily be a 0dBm signal right next to one
that's -80dBm, so the ~ 20-40dB isolation between signals is far from
adequate. I could insert interstitial grounds between the signal pins,
although I was hoping to find something off-the-shelf that already comes with
data, rather than having to sit down and sweep something like the Samtec
connection on my own.
Thanks,
