The Arlon CLTE-AT High Frequency PCB is a high-performance 4-layer printed circuit board specifically engineered for 77GHz radar systems and advanced driver-assistance systems (ADAS). As automotive and aerospace electronics push into higher millimeter-wave frequencies, maintaining signal integrity becomes critical. This board utilizes microglass-reinforced PTFE laminates to provide autonomous systems and RF engineers with exceptional dimensional stability, low insertion loss, and consistent phase performance across varying temperatures.
Key Features
-
Controlled Dielectric Constant: Features a stable DK of 3.00 ($\pm 0.04$) at 10 GHz, ensuring predictable impedance and minimal phase shift at 77GHz frequencies.
-
Low Loss Tangent: Dissipation factor (Df) of 0.0025 minimizes signal attenuation in critical RF paths.
-
4-Layer Stackup Precision: Engineered with precise registration and strict trace width tolerances to handle tight-pitch high-frequency routing.
-
Thermal Reliability: Low Z-axis coefficient of thermal expansion (CTE) at 25 ppm/°C ensures the integrity of plated through-holes (PTH) during thermal cycling.
-
Advanced Surface Finish: Available with immersion silver or ENIG finishes to optimize high-frequency skin effect and preserve solderability.
Applications
-
Automotive Radar: 77GHz adaptive cruise control, collision avoidance, and blind-spot detection systems.
-
Aerospace and Defence: Millimeter-wave radar altimeters, satellite communications, and smart munitions guidance.
-
Telecommunications: 5G/6G infrastructure, high-capacity backhaul antennas, and point-to-point microwave links.
-
Industrial Sensing: Precision level transmitters and high-frequency object detection sensors.
