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.

BNC Connector

BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.

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 BNC and RP-SMA cable assembly is well suited for internal antenna leads in routers, smartphones, and compact IoT devices. The combination of reliable BNC 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.
