SMA Receptacle for 50 Ohm RF Paths Up to 18 GHz
The Amphenol RF 901-10228 is a standard SMA receptacle — female socket, 50 Ohm impedance, rated to 18 GHz. The 50 Ohm characteristic impedance is the baseline for most RF test equipment, antennas, and radio front-ends; the 18 GHz ceiling covers L-band through Ku-band without rolling off the return loss. The threaded coupling (SMA standard 1/4-36 UNS-2A thread) mates with any standard SMA male plug, so the field-replacement path is straightforward — no proprietary keying or non-standard interface to track down.
Panel-Mount Fit and Solder Termination
The centre contact terminates via solder cup or solder post (the contact termination is listed as solder), so the signal lead is hand-soldered to the centre pin after the body is bolted down. The 500 mating cycles with gold-plated beryllium copper centre contact mean this receptacle can survive repeated field connects — typical for test points, antenna ports, or equipment that gets swapped during maintenance.
