With the continuous development of high-definition cameras, 5G communication, ultra-high-definition display, 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 car cameras, the key component that actually handles high-frequency signal transmission is a component called **micro coaxial cable束**. Today, let's learn about it—the reason why it can ensure stable and unobstructed high-frequency signal transmission!
What is a high-frequency signal?
High-frequency signals usually refer to electromagnetic signals with frequencies above 3MHz, especially radio frequency (RF) and microwave signals in the range of tens of MHz to 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 clearer and more real-time the images and data are. However, high-frequency signals also have a "delicate" side:
Susceptible to electromagnetic interference
Easy to衰减；
Extremely sensitive to impedance matching;
Easy to cause reflections and crosstalk.
Therefore, in order to transmit high-frequency signals over a long distance, quickly, and stably, it is necessary to choose professional high-frequency transmission cables.
Why are high-frequency signals "picky" about wire?
In high-frequency transmission ranging from several hundred MHz to several tens of GHz, any minor structure error of the cable material may cause signal attenuation or distortion. Common cables often experience the following problems in high-frequency environments:
Signal reflection
Interference and radiation interference;
Transmission instability leads to packet loss or abnormal images.
This is why in high-precision applications (such as camera modules, 5G communication modules, medical imaging systems, etc.), ordinary wire materials often fail to meet the demands.
Why can the extremely 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 line (commonly 50Ω or 75Ω), which effectively suppresses signal reflection and standing wave phenomena, ensuring signal integrity and consistency.
Multilayer shielding structure—strong anti-interference performance
Extremely thin coaxial cables usually use 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 their own signal radiation from affecting other circuits.
Low-loss insulating material—clearer signals
Insulation layers are commonly made of materials with low dielectric constants such as FEP, ETFE, etc., which have very low loss at high frequencies. Even at GHz levels of transmission, they can maintain low attenuation and high fidelity.
Super soft structure - meets precise assembly
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-fine coaxial cable束, with its constant impedance, multi-layer shielding, low-loss insulation, and super-flexible characteristics, has become the core connecting component for ensuring smooth signal transmission, clear images, and stable data. Whether you are engaged in mobile phone, drone, medical equipment, or automotive electronics research and development, Micro Coaxial Cable is a key component that cannot be ignored in your high-frequency design!
