How to achieve low loss and high stability in high-speed interconnections for extremely thin coaxial束?

With the accelerated popularization of applications such as 5G communication, ultra-high-definition imaging, and artificial intelligence, the requirements for high-speed signal transmission of equipment are continuously increasing. Traditional cables often face problems such as signal loss and severe interference in high-frequency environments, while ultra-fine coaxial cables (Micro Coaxial Cable) are becoming an important solution in the field of new-generation high-speed interconnection, thanks to their precise structural design and excellent electrical characteristics.

One, structural advantages determine performance: precise impedance matching
The ultra-fine coaxial cable is composed of multiple layers including the central conductor, insulating layer, shielding layer, and outer sheath. This typical "coaxial" design ensures that the signal maintains a stable characteristic impedance throughout the transmission process, effectively preventing signal reflection or loss caused by impedance mismatch.
In high-frequency transmission applications, stable impedance matching means lower bit error rates and higher signal integrity, which is the foundation for achieving high-speed and reliable communication.

Low insertion loss, purer signal transmission
In high-speed signal channel design, "insertion loss" is one of the key performance indicators. Compared with traditional FPC or jumper wire solutions, ultra-fine coaxial cables can significantly reduce insertion loss under the same conditions, ensuring the integrity and clarity of the signal transmission through the cable bundle.
It is of great significance for applications with extremely high bandwidth requirements, such as high-definition video transmission, millimeter-wave radar perception, and VR/AR display modules.

Excellent shielding and anti-interference capability
In high-frequency environments, electromagnetic interference (EMI) and crosstalk often weaken signal quality. The outer shield layer of extremely thin coaxial cables usually adopts copper braid or multi-layer shielding structure, which can effectively isolate external electromagnetic waves and suppress crosstalk between adjacent signal lines.
Therefore, Micro Coax can maintain stable signal output in complex electromagnetic environments, whether it is in vehicle radar systems, industrial equipment, or high-speed camera modules.

Four, combines flexible structure and mechanical durability
In addition to excellent electrical properties, ultra-fine coaxial cables also have outstanding mechanical flexibility. With a small wire diameter and low bending radius, they can withstand multiple folds and bends without affecting signal performance, making them very suitable for dynamic movement structures of devices such as laptop hinges, tripod cameras, drones, and other similar applications.
This "high flexibility + high stability" characteristic brings more layout freedom to engineering design.

Five, the potential of high bandwidth for the future
With the collaborative design of high-precision conductors, low-loss insulating media, and high-quality shielding materials, the micro coax has been able to support working frequencies of tens of GHz, corresponding to data transmission rates of up to 64Gbps and even higher.
It not only meets the current needs of 5G and high-speed computing, but also provides sufficient technical space for future 8K image transmission, AI edge devices, and next-generation communication modules.

Extremely fine coaxial cable束, with its comprehensive advantages of low loss, strong anti-interference, high flexibility, and ultra-high bandwidth, has become the preferred solution for high-frequency signal interconnection. From structural design to material application, every link focuses on the core goal of "high-speed stability," providing a solid signal foundation for the next generation of intelligent devices.
