A coaxial cable is a type of transmission line specifically designed for high-frequency and RF signal transmission. It features a concentric structure consisting of a center conductor, dielectric insulator, shielding layer, and outer jacket, which provides stable, low-loss, and interference-resistant signal transmission.
Thanks to its excellent shielding performance and precise impedance control, coaxial cable is widely used in wireless communications, RF modules, antenna systems, video transmission, and measurement equipment, making it an essential material in RF engineering.
The coaxial structure effectively reduces signal reflection and loss, supporting applications from MHz to GHz and even higher frequencies.
Single- or multi-layer braiding and foil shielding effectively block external electromagnetic interference (EMI), ensuring signal integrity.
Common impedances include 50Ω and 75Ω, suitable for communication, broadcasting, and measurement systems.
Available in various flexibility and bend-resistance grades, ideal for mobile devices or space-constrained cabling requirements.
A wide range of configurations—cable diameter, jacket material, conductor material (CU / CCS / CCA), insertion loss, and more—can be customized to meet specific needs.
Low loss with standardized construction; suitable for RF modules, antenna extension cables, and general communication equipment.
Ultra-thin diameter with high flexibility; commonly used in smartphones, wireless modules, IoT devices, and wearables.
Improved insertion loss performance; ideal for base stations, long-distance outdoor antennas, and professional communication systems.
Used for surveillance systems, satellite TV, broadcasting equipment, and CCTV.
With its outstanding RF performance and strong immunity to interference, coaxial cable serves as a fundamental transmission interface for modern communication and high-frequency electronic equipment. Selecting the appropriate cable type and specifications for different application scenarios can significantly enhance signal quality and system reliability, ensuring stable and efficient product operation.
