Extremely fine coaxial cable束：for faster, more stable, and clearer high-frequency signals

With the continuous development of high-definition cameras, 5G communication, ultra-high-definition displays, medical equipment, and precision electronic products, the performance requirements for high-frequency signal transmission are becoming more stringent. You may have heard of "coaxial cable," but do you know? In devices such as smartphones, drones, endoscopes, and vehicle-mounted cameras, it is actually a key component named **Micro Coaxial Cable** that is responsible for high-frequency signal transmission. Today, let me introduce it to you — why it can ensure stable and unimpeded high-frequency signal transmission!

What is high-frequency signal?
High-frequency signals usually refer to electromagnetic signals with frequencies above 3MHz, particularly radio frequency (RF) and microwave signals in the range of several tens of MHz to several tens of GHz. In fields such as wireless communication, high-definition imaging, radar detection, and medical imaging, the higher the signal frequency, the faster the data transmission speed, and the better the clarity and real-time performance of images and data. However, high-frequency signals also have a "delicate" side:
  Susceptible to electromagnetic interference;
• Easily attenuated;
Extremely sensitive to impedance matching;
Easy to cause reflection and crosstalk.
Therefore, in order to transmit high-frequency signals over long distances, quickly, and stably, it is necessary to choose professional high-frequency transmission cables.

Why are high-frequency signals "picky" about wire materials?
In high-frequency transmission ranging from a few hundred MHz to several tens of GHz, any minor structure error of the cable material may cause signal attenuation or distortion. In a high-frequency environment, ordinary cables often encounter the following issues:
Signal reflection
Interference and radiation interference;
Transmission instability leads to packet loss or image anomalies.
This is why in high-precision applications (such as camera modules, 5G communication modules, medical imaging systems, etc.), ordinary wires often fall short of expectations.

Why can the ultra-fine coaxial cable (Micro Coaxial Cable) stabilize high-frequency signals?
Constant Impedance Design - Prevent Signal Reflection
Micro Coaxial Cable adopts a standardized coaxial structure, maintaining a constant impedance throughout the cable (commonly 50Ω or 75Ω), which effectively suppresses signal reflections and standing wave phenomena, ensuring signal integrity and consistency.
Multi-layer shielding structure - strong anti-interference performance
Extremely thin coaxial cables usually employ a double-layer or even multi-layer shielding design with copper foil and woven mesh, which can effectively isolate external electromagnetic interference (EMI) and prevent the self-signal radiation from affecting other circuits.
Low-loss insulating material—clearer signals
Insulation layers commonly use materials with low dielectric constants such as FEP and ETFE, which have extremely low loss at high frequencies. Even at GHz-level transmission, they can maintain low attenuation and high fidelity.
Super soft structure - meets precise assembly requirements
Extremely thin coaxial cables have a very small diameter and bend radius, which are very suitable for complex space wiring, such as mobile phone, drone camera, endoscope module, and other micro-space applications.

In various high-frequency signal transmission scenarios, ultra-thin coaxial cable束, with its constant impedance, multi-layer shielding, low-loss insulation, and super-flexible characteristics, has become the core connection component ensuring smooth signal transmission, clear picture quality, and stable data. Whether you are engaged in mobile phone, drone, medical equipment, or in-vehicle electronic research and development, Micro Coaxial Cable is a key component that you cannot ignore in high-frequency design!
