How to improve the high-speed transmission performance of ultra-fine coaxial cable assemblies for KEL USLS20-30

In the context of continuously upgraded high-speed digital devices, the extremely thin coaxial cable (Micro Coaxial Cable) has become the core connection solution for fields such as laptop computers, smart terminals, medical imaging, and vehicle displays due to its characteristics of thinness, flexibility, and high resistance to interference. However, in practical applications, many engineers encounter problems such as insufficient transmission speed, increased error rate, and significant signal attenuation. This article will analyze the reasons behind these issues and introduce an excellent product in the high-speed connection field—the KEL USLS20-30 connector and its paired extremely thin coaxial cable assembly.

The reasons for the failure to meet the specifications of the extremely fine coaxial cable speed

1. Insufficient performance of wire material
The precision of the ultra-fine coaxial conductor, the quality of the insulating material, and the integrity of the shielding layer directly affect the signal quality. If there is a large deviation in the conductor impedance, insufficient shielding density, or uneven material, it will lead to signal reflection and increased crosstalk, making it difficult for high-speed signals to pass stably.

Connector match is not high

In high-speed harnesses, the importance of connectors is equal to that of cables. If the connectors have poor impedance, Pin structure, or contact reliability, it will cause signal loss and poor contact, leading to a decrease in speed. Some low-cost connectors are particularly prominent in this aspect.

Imprudent assembly process

Solder joint offset, loose crimping, and chaotic harness arrangement can all lead to discontinuity in the signal path, causing high-speed signal reflections, jitter, and an increase in error rate, ultimately affecting overall speed performance.

4. EMI Electromagnetic Interference Impact
Although ultra-fine coaxial cables have a shielding structure, improper shielding grounding or if the cable bundle is too close to the interference source, they may still be affected by electromagnetic waves, leading to signal attenuation and speed reduction.
