The Amphenol RF 901-9893-RFX is a 50 Ohm SMA receptacle with a female socket centre contact, designed for panel-mount RF feedthrough applications where a bulkhead pass-through or cable-to-chassis interface needs a matched-impedance path up to 18 GHz. The flange mounting feature lets you bolt it to a panel or enclosure wall, and the solder cup termination accepts a coaxial cable centre conductor directly — no crimp tool required in the field.
Why the 18 GHz and 500-Cycle Ratings Matter for Your RF Path
The 18 GHz max frequency means this SMA jack supports the full L, S, and C bands plus most of the Ku band — it handles 5G FR1 backhaul, Wi-Fi 6E, satellite downlinks, and instrumentation signals without rolling off. If your application needs more than 500 cycles, step up to a stainless-steel SMA variant with a longer cycle life — but for test-fixture or field-install duty, 500 cycles is the standard SMA endurance.
Panel Mount and Solder Cup — What the Termination Tells You
The flange mounting feature and threaded fastening together mean this receptacle is meant to be bolted to a panel with the mating SMA plug tightened by its coupling nut — the flange takes the mechanical load off the solder joint. The solder cup termination is the traditional field-serviceable method: strip the cable, tin the centre conductor, and solder it into the cup. No special crimp die set needed, which makes this a practical choice for prototype builds, repair kits, and low-volume production where tooling investment isn't justified.
