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.

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.

TNC Connector

TNC (Threaded Neill–Concelman) is the threaded version of BNC, offering improved performance up to 11 GHz and better vibration resistance through its screw coupling. It is commonly used in mobile radio antennas, avionics, and outdoor installations where BNC's bayonet lock would not provide sufficient mechanical security.

Common Applications

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