What This Dual BNC Jack Does in the RF Path
The Amphenol RF 031-6576 is a dual-port BNC jack — two female coaxial connectors in one body, sharing a single panel cutout. It carries the standard 50 Ohm impedance for RF signal paths and is rated to 1 GHz with a 0.2 dB insertion loss across the band.
Why the 2-Port Body Matters for Panel Layout
The 031-6576 carries two ports on one flange, while the single-port sibling 031-5538-10RFX carries one. The difference is panel density — the dual-port body fits two coaxial connections in the space of one standard BNC cutout, which matters when you are routing multiple RF channels through a crowded rear panel. The single-port 031-5538-10RFX comes in bulk packaging; the 031-6576 ships in a tray.
Mounting and Termination — What the Right-Angle Tail Means
This jack mounts through a bulkhead panel with a front-side nut and terminates to the PCB through right-angle solder tails. The right-angle orientation means the cable enters perpendicular to the board edge — typical for rack-mount equipment where the RF I/O panel sits at 90° to the main PCB. The shield termination is a solder connection to the shell, not a press-fit ground tab.
