FME Jack for RG-174/188A/316 — 50 Ohm, 2 GHz
The TE Connectivity 1-1337551-0 is an FME-style jack (female socket) coaxial connector, built for 50 Ohm systems and rated to 2 GHz. It comes as a kit: one connector body, one center contact, one ferrule, and one coupling nut — everything needed to terminate a cable in one order. It's designed for RG-174A, RG-188A, and RG-316 cable — the three most common small-diameter coax types for short-run RF interconnects in telecom and instrumentation.
Shield termination is crimp; the center contact is soldered. The cable group — RG-174A, 188A, 316 — all share a similar 0.100-inch (2.54 mm) dielectric diameter, so the same ferrule and contact geometry work across them. If you are terminating RG-316 specifically, this connector is a direct fit. The threaded coupling nut provides a vibration-resistant mate that holds up to 500 mating cycles, which is solid for field-service gear that gets swapped during maintenance rounds.
RF Performance and Operating Range
Rated to 2 GHz with a typical insertion loss of 0.2 dB, this jack covers the ISM bands, cellular, and GPS /L2 without breaking a sweat. The 50 Ohm impedance is standard for most RF test and measurement, antenna feeds, and short cable assemblies — no impedance mismatch to chase at the board edge.
