The BNC7T-J-P-GN-ST-TH1: That frequency ceiling is unusual for a 75 Ohm BNC; most video-grade BNCs top out around 1-2 GHz. The PTFE dielectric and gold-plated center contact are what let it hold a clean signal path that high. The nickel-plated brass body and silver housing are standard for the series. This is the jack half for a 75 Ohm BNC interconnect, built for broadcast, CCTV, and high-frequency video distribution where the line carries DC bias for remote preamps.
The 12 GHz max frequency is the headline spec here. On a 75 Ohm BNC, 12 GHz is well into the microwave region — typical 75 Ohm BNCs are rated for baseband video (DC to a few hundred MHz) or at most 1-2 GHz. This jack covers 4K and 8K UHD video carriers, satellite IF distribution at L-band (950-2150 MHz), and DOCSIS 3.1 upstream frequencies with headroom. The gold center contact plating ensures the mating interface resistance stays low over repeated connect-disconnect cycles — important when the signal is at 12 GHz where a few milliohms of contact noise eats into the link budget.
Solder Termination — Board Layout Fit
The center pin solders into a plated through-hole; the shield legs solder into the board ground plane. No crimp tool needed, no ferrule. The bayonet lock is the standard BNC quarter-turn coupling; it mates with any 75 Ohm BNC plug that has the same interface dimensions. The jack is a single-port, female socket configuration.
