The TE Connectivity 3-1478963-0 is a Greenpar series SMA receptacle — a female socket, 50 Ohm impedance, panel-mounted with a flange, and terminated via solder cup. This is a single-port, threaded-fastening connector meant for bulkhead or chassis-wall mounting where a clean RF feedthrough is needed — think test equipment, antenna ports, or enclosure pass-throughs where the cable is soldered in and the connector stays put.
Why the 50 Ohm and 6 GHz ratings matter for your signal path
The 6 GHz max frequency means it will pass a clean signal up through the C-band; above that, insertion loss climbs and the VSWR degrades. The 500 mating cycles rating is high for an SMA — the gold-on-gold contact interface (center contact gold-plated, body gold-plated) resists fretting corrosion through repeated connect-disconnect cycles, which matters if this port sees regular test cable hookups.
Mounting and termination — what the flange and solder cup mean for installation
The panel mount with flange means this receptacle bolts to a chassis or enclosure wall using the four flange holes — the threaded body passes through the panel and the nut secures it from the opposite side. The solder cup termination is a field-serviceable method: you strip the coaxial cable, tin the center conductor, and solder it into the cup. This is a permanent install — no crimp tool needed, but rework requires desoldering. The threaded fastening ensures the mating SMA plug stays locked under vibration, common in benchtop or rack-mount gear.
