About This Assembly

1.37 Cable

1.37mm coaxial cable is a miniature 50-ohm cable slightly larger than 1.13mm, balancing compact size with improved power handling and lower signal loss. Used for internal antenna leads in smartphones, routers, and IoT devices where the 1.13mm cable would be too lossy but space constraints still prohibit larger coax.

FME Connector

FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.

RP-SMA Connector

RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.

Common Applications

This FME and RP-SMA cable assembly is well suited for internal antenna leads in routers, smartphones, and compact IoT devices. The combination of reliable FME and RP-SMA connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
