RO3003G2 2-Layer PCB 0.2mm Thin Board with Immersion Gold for Automotive Radar Applications

1.Introduction to RO3003G2 Material

RO3003G2 high-frequency laminates represent Rogers' advanced solution for millimeter-wave automotive radar needs. Developed based on industry feedback, these ceramic-filled PTFE composites feature:
Specially formulated resin/filler system for reduced insertion loss
Homogeneous construction with VLP ED copper (16/17/18 ppm/°C CTE)
Enhanced thermal stability (-35 ppm/°C Dk coefficient)
Ultra-low dielectric loss (0.0011 @10GHz)

This makes RO3003G2 ideal for 77GHz radar modules where signal integrity is critical.
