RO3003G2 PCB 5mil 2-layer Immersion Gold Circuits
The Rogers RO3003G2 is a high-performance, ceramic-filled PTFE laminate designed for millimeter wave automotive radar applications. This latest iteration of Rogers' industry-leading RO3003 solutions was developed based on customer feedback to address the next-generation needs of ADAS (Advanced Driver Assistance Systems) like adaptive cruise control, forward collision warning, and lane change assist.
Key Features:
- Dielectric constant (Dk) of 3.0 ±0.04 at 10 GHz and 3.07 at 77 GHz
- Low dissipation factor of 0.0011 at 10 GHz
- Excellent thermal coefficient of dielectric constant (-35 ppm/°C)
- Very low profile (VLP) electrodeposited (ED) copper
- Copper-matched coefficient of thermal expansion (CTE) for enhanced reliability
- Homogeneous construction with reduced dielectric porosity
