In today's rapid development of intelligent driving and autonomous driving technology, millimeter wave radar has become an indispensable core component of vehicle perception systems. It achieves precise detection of the surrounding environment through high-frequency electromagnetic waves such as 77GHz. However, to ensure that the radar maintains a stable and accurate working state under various complex conditions, the reliability of internal signal transmission is crucial. And the key connection here is the extremely fine coaxial cable (Micro Coaxial Cable).
The key role of ultra-fine coaxial beam
In millimeter wave radar modules, it is necessary to simultaneously transmit high-speed radio frequency signals and high-speed digital signals. Any minor interference or attenuation can lead to a decrease in radar detection accuracy. The extremely thin coaxial beam, with its excellent electrical performance, effectively ensures the integrity and stability of the signals, which is mainly reflected in the following aspects:
High impedance consistency:
Ensure signal matching between the radar chip and antenna module to avoid reflections and distortions, thus guaranteeing the integrity of signal transmission.
Low-loss transmission:
Even at 77GHz and other high-frequency bands, ultra-thin coaxial beam can still effectively reduce signal attenuation, providing a stable channel for millimeter-wave signals.
Compact structure
The wire diameter is usually between 0.3mm and 0.5mm, which is very suitable for miniaturized radar module design, leaving more layout space for complex systems.
Addressing the Challenges of Harsh Vehicle Environments
The vehicle radar must not only have precise detection capabilities but also must adapt to multiple environmental tests such as high temperatures, low temperatures, vibrations, and strong electromagnetic interference. The extremely thin coaxial cable束, in its design, uses high flexibility insulating materials and high-density shielding structures, which can not only flexibly route the cables in limited spaces but also significantly enhance the anti-interference performance.
It can maintain signal stability under rain, snow, tunnel driving, or high-speed vibration conditions, ensuring that the radar continuously outputs reliable data and provides solid support for the vehicle perception system.
Chapter 3: Technological Evolution and Future Trends
With the increasing requirements for millimeter wave radar resolution and detection accuracy in intelligent driving systems, the internal signal transmission harnesses are also continuously upgraded. The future ultra-thin coaxial harnesses will trend towards smaller diameters, higher frequency bands, and better shielding to meet the more rapid and complex communication needs.
It is not only an important part of radar performance optimization, but also a key guarantee for the safe and reliable operation of advanced driver-assistance systems (ADAS).
The ultra-fine coaxial cable bundle plays a crucial role in the signal transmission of automotive millimeter-wave radar. Although it is not eye-catching, it is the "invisible hero" that ensures the accuracy of radar detection and the stable operation of the system.
