Between-Series RF Adapter: SMA Jack to U.FL Jack
The Amphenol 901-10175 is a straight between-series adapter that converts an SMA Jack, female socket to a U.FL (UMCC) Jack, male pin. It mounts through a bulkhead panel using the included lockwasher and nut, making it a fixed chassis feedthrough for routing a U.FL signal path to an SMA test port or cable assembly. Gold-over-beryllium copper centre contacts and 100 mating cycles mean this adapter is built for repeated connect-disconnect duty in field service or lab use — not a one-time solder-and-forget part.
Bulkhead Mounting and Included Hardware
The bulkhead mounting feature means the SMA side threads through the panel from the inside, and the U.FL side stays on the outside for cable attachment. Fastening is mixed: the SMA end uses a threaded coupling nut (standard SMA interface), while the U.FL end uses a snap-on latch. That snap-on interface is the weak link for retention — the U.FL side is designed for low-profile internal connections, not high-pull cable runs. Keep the cable strain-relieved near the adapter body.
