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.

SMA Connector

SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.

Common Applications

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