Material Introduction
The high-frequency, ceramic-filled PTFE laminates of Rogers RO3003G2 are an extension of Rogers' industry-leading RO3003 solutions. The development of RO3003G2 laminates is based on industry feedback, with a special focus on addressing the next generation needs for millimeter wave automotive radar applications.
The incorporation of an optimized resin and filler content, along with the utilization of Very Low Profile ED copper provides a reduced insertion loss. This characteristic makes RO3003G2 laminates well-suited for implementation in Advanced Driver Assistance Systems (ADAS) such as adaptive cruise control, forward collision warning, active braking, and lane change assist.
Features
1. The dielectric constant of 3.00 at 10 GHz and 3.07 at 77 GHz.
2. Very Low Profile (VLP) ED copper.
3. Homogeneous construction incorporating VLP ED copper and reduced dielectric porosity.
4. Enhanced filler system.
Benefits
1. Best-in-class performance for insertion loss.
2. Minimize variation in dielectric constant in the finished PCB.
3. Enable the trend towards using smaller diameter vias; Enhanced filler system using small rounded particles
4. Global manufacturing footprint.
