RO3003G2 High-Frequency PCB: Advanced Solutions for Automotive Radar Applications
(Printed Circuit Boards are custom-made products; the images and parameters shown are for reference only.)
The Rogers RO3003G2 laminates are high-frequency, ceramic-filled PTFE materials, building on Rogers' industry-leading RO3003 solutions. Developed in response to industry feedback, RO3003G2 is specifically designed to meet the demands of millimeter wave automotive radar applications.
These laminates incorporate an optimized resin and filler content, along with Very Low Profile (VLP) ED copper, which significantly reduces insertion loss. This makes RO3003G2 laminates highly suitable for Advanced Driver Assistance Systems (ADAS), including adaptive cruise control, forward collision warning, active braking, and lane change assist.
Features
1.Dielectric Constant: 3.00 at 10 GHz and 3.07 at 77 GHz.
2.Very Low Profile (VLP) ED Copper: Enhances performance.
3.Homogeneous Construction: Incorporates VLP ED copper and reduced dielectric porosity.
4.Enhanced Filler System: Improves overall laminate quality.
Benefits
1.Best-in-Class Insertion Loss Performance: Ensures minimal signal loss.
2.Minimized Variation in Dielectric Constant: Provides consistency in finished PCBs.
3.Smaller Diameter Vias: Supports advanced design techniques with enhanced filler systems using small rounded particles.
4.Global Manufacturing Footprint: Ensures availability and support worldwide.
