How to achieve low loss and high stability in high-speed interconnects for extremely fine coaxial beam?

With the rapid popularization of applications such as 5G communication, ultra-high-definition imaging, and artificial intelligence, the requirements for high-speed signal transmission of equipment are constantly 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 due to their precise structural design and excellent electrical properties.

The structural advantage determines the performance: precise impedance matching
The extremely 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 error rate and higher signal integrity, which is the foundation for achieving high-speed and reliable communication.

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

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

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

Five, the high bandwidth potential 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 demand for 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 thin 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.
