Today, with the 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 stable and accurate operation under various complex working conditions, the reliability of internal signal transmission is crucial. And the key connection among them is the extremely thin coaxial cable (Micro Coaxial Cable).
The key role of extremely 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 will lead to a decrease in radar detection accuracy. The extremely fine coaxial cable束, 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, thereby guaranteeing the integrity of signal transmission.
Low-loss transmission
Even at high-frequency bands such as 77GHz, extremely thin coaxial cable束 can still effectively reduce signal attenuation, providing a stable channel for millimeter wave signals.
Tightly structured
The wire diameter is usually between 0.3mm and 0.5mm, which is very suitable for the design of miniaturized radar modules, leaving more layout space for complex systems.
Dealing with the challenges of harsh vehicle-mounted environments
The vehicle radar must not only have accurate detection capabilities but also adapt to multiple environmental tests such as high and low temperatures, vibration, and strong electromagnetic interference. The extremely thin coaxial cable束is designed with high flexibility insulation materials and high-density shielding structures, which can not only flexibly route wires in limited spaces but also significantly enhance the anti-interference performance.
It can maintain signal stability in all weather conditions, tunnel driving, or high-speed vibration, ensuring that the radar continuously outputs reliable data and provides a solid support for the vehicle perception system.
III. Technological Evolution and Future Trends
With the continuous improvement of resolution and detection accuracy requirements for millimeter-wave radar in intelligent driving systems, the internal signal transmission cable harness is also continuously upgraded. The ultra-thin coaxial cable harnesses in the future 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).
Extremely fine coaxial cable束 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 precise detection of the radar and the stable operation of the system.
