With the rapid development of modern electronic and communication equipment, the reliability and stability of the signal transmission system have become one of the core competitiveness factors. As devices gradually evolve towards miniaturization, lightweight, and high-frequency directions, traditional cables are no longer able to meet the dual demands of space constraints and high-speed transmission. Micro Coaxial Cable has emerged as a result, and with its extremely small size, high-speed signal transmission capabilities, and excellent anti-interference performance, it is widely used in various precision electronic systems.
Definition and Characteristics of Micro Coaxial Cable
Micro Coaxial Cable is a tiny coaxial structure signal transmission cable with both high-frequency transmission capabilities and excellent electromagnetic compatibility performance. This type of cable is composed of micro coaxial cable and dedicated connectors, suitable for applications with extremely high requirements for signal integrity, such as ultra-thin laptops, smartphones, medical imaging equipment, 5G antenna modules, and vehicle-mounted cameras.
Its significant advantages include:
Support high-speed data and high-frequency signal transmission;
• Takes up less space, suitable for high-density wiring;
• Excellent anti-bending and anti-interference performance;
• Meet stringent industrial and consumer electronics design requirements.
Part Two: Structural Composition and Performance Points
The typical structure of Micro Coaxial Cable consists of four layers, each playing a crucial role in signal stability and anti-interference performance:
Inner conductor:
Silver-plated copper wire is usually used for high-speed signal transmission, featuring low impedance and excellent conductivity.
Insulation layer:
Select high-performance materials such as FEP and PTFE to ensure electrical insulation and maintain the stability of characteristic impedance.
Weave the shielding layer.
Utilizing ultra-fine silver-plated copper wire high-density weaving, effectively suppresses external electromagnetic interference (EMI), ensuring signal integrity.
Jacket layer:
As the outermost protective layer, materials such as FEP or PU are commonly used, which not only improve flexibility and wear resistance but also extend the cable lifespan.
Through precise structural design and high-quality material selection, the Micro Coaxial Cable can achieve stable impedance control and excellent electromagnetic shielding effect under extremely thin wire diameters.
Typical Applications and Development Trends
With high-speed transmission and lightweight design becoming the mainstream trend in electronic design, the application fields of Micro Coaxial Cable continue to expand.
Consumer electronics: ultra-thin laptops, high-speed internal connections in smartphones.
• Communication and 5G field: RF module, antenna connection;
Medical equipment: signal transmission of high-resolution imaging systems;
Car Electronics: Vehicle-mounted cameras and ADAS systems.
In the future, with the development of AI terminals, wearable devices, and intelligent vehicle technology, the demand for high-frequency, high-flexibility harnesses will further increase, and the importance of Micro Coaxial Cable will also continue to rise.
Micro coaxial cable has become an indispensable core interconnection component in modern high-density electronic systems, thanks to its excellent high-frequency performance, stable signal transmission capability, and compact structural design.
