The Amphenol RF 132171RP is a between-series coaxial adapter that converts an SMA Plug, Male Pin interface to an RP-SMA Jack, Male Pin interface.
Why the 18 GHz and 50 Ohm Ratings Matter
The 18 GHz maximum frequency means this adapter covers the full L, S, C, and X bands, plus the lower Ku band — enough headroom for most Wi-Fi, cellular backhaul, and satellite communication links. The gold plating on both the body and the center contact keeps insertion loss stable over repeated matings in corrosive or outdoor environments.
SMA vs RP-SMA — What This Adapter Solves
Standard SMA connectors have a male pin on the plug and a female socket on the jack. Reverse-polarity SMA (RP-SMA) swaps the gender: the plug has a female socket and the jack has a male pin. The 132171RP takes a standard SMA plug (male pin) and converts it to an RP-SMA jack (male pin), so you can mate a standard SMA male cable to an RP-SMA female device (common on Wi-Fi access points and antennas). The threaded, threaded fastening on both ends provides vibration-resistant coupling.
The 132171RP is the straight, male-to-male center gender version. The 132172RP is a right-angle body with the same conversion.
