What Are Radar-Grade PCBs?
Radar PCBs are high-precision high-frequency circuit boards tailored for microwave and millimeter-wave radar systems. Differing from standard PCBs, they focus on ultra-low signal loss, precise impedance control, stable phase performance and reliable electromagnetic shielding. Supporting 24GHz to 77GHz high-frequency transmission, they deliver accurate ranging, speed measurement and obstacle detection, acting as the core hardware foundation for intelligent radar perception equipment.
- Ultra-Low High-Frequency Signal Loss: Adopts low Dk/Df dielectric substrates to reduce high-frequency signal attenuation and phase deviation, maintaining high-sensitivity radar detection performance.
- Micron-Level Precision Stability: Strict layer alignment and impedance control avoid signal distortion, ensuring consistent ranging accuracy and stable beamforming performance.
- Excellent Electromagnetic Shielding Performance: Integrated full ground layer and isolated layout suppress external electromagnetic interference, effectively reducing radar noise and false detection rates.
