Specs Summary
About This Assembly
1.13 Cable
1.13mm coaxial cable is an ultra-miniature 50-ohm cable used primarily for internal RF wiring in compact wireless devices such as laptops, tablets, and embedded modules. Its extremely small 1.13mm outer diameter allows it to pass through tight spaces inside consumer electronics, connecting antennas to WiFi or cellular modules with minimal signal loss over short distances.
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 WiFi and cellular module antenna connections in laptops and tablets. 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.
