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 ability 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, braid layer, and outer sheath, and has the following advantages:
Tiny in volume, high in flexibility, suitable for wiring in narrow spaces.
The 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 signal transmission scenarios with high density, high frequency, and low loss, such as notebook computers, tablets, camera modules, and medical imaging systems, and other precision equipment.
Why high-frequency signals cannot do without extremely thin coaxial cables?
High-frequency signals are susceptible to external electromagnetic interference, signal reflection, and crosstalk during transmission, thereby causing signal attenuation and delay.
The ultra-fine coaxial cable, with precise impedance control and an 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 there is a very high requirement for signal clarity, the ultra-fine coaxial cable can maintain high fidelity and high stability in signal transmission.
