With the continuous evolution of high-definition camera module, wearable devices, and medical electronics technology, products are putting higher requirements on internal wiring space and signal transmission performance. Traditional cables are difficult to balance performance and reliability in scenarios with limited space and high-speed transmission, while Micro Coaxial Cable (extremely thin coaxial cable) is gradually becoming the preferred solution for high-end electronic products thanks to its excellent high-frequency characteristics and flexible structure. This article will introduce to you—the unique advantages of 38AWG extremely thin coaxial cable in terms of high-frequency performance.
What is 38AWG ultra-fine coaxial cable?
"AWG" is the abbreviation for American Wire Gauge (American Wire Gauge), and the larger the number, the finer the wire diameter. 38AWG represents a conductor diameter of only about 0.1mm, finer than a hair, yet it can stably transmit high-speed, high-frequency signals. This astonishing "small size, high performance" feature is exactly the technical charm of Micro Coaxial Cable.
Why is high-frequency performance so crucial?
In high-speed digital signal, high-definition video, and RF transmission, the higher the signal frequency, the more stringent the requirements for the signal integrity and anti-interference performance of the cables. Ordinary flat flex cables (FFC/FPC) are prone to signal attenuation and crosstalk in high-frequency environments, while the coaxial structure, with its complete shielding system of central conductor-insulating layer-shielding layer-outer sheath, can effectively suppress signal loss and external interference, ensuring the stable operation of high-speed systems.
Three, high-frequency performance advantages of 38AWG ultra-fine coaxial cables
Lower insertion loss
The 38AWG ultra-thin coaxial cable adopts a multi-strand braided conductor plus a high-density woven shielding structure, which can significantly reduce power loss during signal transmission. Even at frequencies of 6GHz and above, it can still maintain high stability and low loss performance.
Excellent impedance control capability
The coaxial structure naturally possesses a stable characteristic impedance (commonly 50Ω or 75Ω). Even at micrometer-scale dimensions, 38AWG cables can achieve extremely high consistency, avoiding signal reflection and echo loss, providing reliable protection for high-speed digital and radio frequency signals.
Excellent EMI anti-interference performance
High-density woven shielding layer combined with ultra-fine conductors can effectively suppress electromagnetic interference (EMI) and enhance the signal integrity of the system. Whether it is a 5G terminal, vehicle-mounted radar, or medical imaging equipment, it can all achieve a more stable high-frequency transmission environment.
Superior flexibility and high-density wiring adaptability
The 38AWG ultra-fine coaxial cable has an extremely thin diameter and small bending radius, making it suitable for devices with narrow spaces and complex wiring, such as wearable bracelets, endoscope modules, and so on. While maintaining high-frequency performance, it still meets stringent bending and dynamic usage requirements.
With its outstanding high-frequency transmission performance, excellent anti-interference ability, and flexible wiring characteristics, the 38AWG ultra-thin coaxial cable is becoming an ideal choice in fields such as 5G terminals, vehicle-mounted electronics, medical imaging, and smart wearables. As high-frequency and high-speed application scenarios increase, Micro Coaxial Cable will continue to be a key component for improving signal transmission quality and system performance.
