With the continuous development of 5G communication, medical equipment, high-end imaging systems, and consumer electronics towards miniaturization and high-speed, the stability and anti-interference capability of signal transmission have become particularly important. Under this trend, ultra-fine coaxial cables (Micro Coaxial Cable) have become an indispensable core component in high-frequency signal systems, thanks to their excellent high-frequency transmission performance and flexible structural design.
What is ultra-fine coaxial cable?
Micro coaxial cable is a miniature high-frequency transmission cable with a multi-layer shielding structure. It consists of an inner conductor, insulation layer, braided layer, and outer sheath, and has the following advantages:
Micro in volume, high flexibility, adaptable for wiring in narrow spaces.
Multi-layer shielding structure ensures excellent anti-interference performance.
Impedance control is precise, signal attenuation is extremely low.
This type of cable is particularly suitable for high-density, high-frequency, and low-loss signal transmission scenarios, such as laptops, tablets, camera modules, and medical imaging systems and other precision equipment.
Why can't high-frequency signals do without extremely thin coaxial cables?
High-frequency signals are prone to external electromagnetic interference, signal reflection, and crosstalk during transmission, which can lead to signal attenuation and delay.
The ultra-fine coaxial cable, through precise impedance control and efficient shielding design, can effectively reduce signal loss and ensure the integrity and stability of the signal during high-speed transmission. For example, in applications such as camera modules, display panels, and medical endoscopes, where high signal clarity is required, the ultra-fine coaxial cable can maintain high fidelity and stability in signal transmission.
