SMA Receptacle for Panel-Mount RF Interconnects
The 1-1478963-0: The gold-plated stainless steel body provides corrosion resistance and mechanical strength for threaded coupling, while the PTFE dielectric maintains stable impedance across the frequency range.
The 18 GHz max frequency means this connector handles the full SMA band without a roll-off penalty — suitable for test equipment, microwave links, and instrumentation up to 18 GHz. The solder cup termination accepts coaxial cable directly; no crimp tool is needed, but the solder joint quality directly affects RF performance up to the band edge.
Panel mount with a flange — the connector secures to a bulkhead or chassis panel via the flange, not to a PCB. The threaded fastening type (standard SMA thread) mates with any SMA male plug. Termination is solder cup: the centre conductor and shield are soldered to the cup and body respectively, a common method for semi-rigid or flexible coaxial cable assemblies.
