Rogers Corp. has launched the latest addition to the RO3000® series of PTFE circuit materials, the RO3003G2™ for automotive radar and other high frequency applications.
The RO3003G2 high frequency laminates build on the RO3003™ platform, providing improved insertion loss and reduced dielectric constant (Dk) variation. The combination of optimized resin and filler content with very low profile electrodeposited (VLP ED) copper provides a Dk of 3 at 10 GHz, measured using the clamped stripline method, and 3.07 at 77 GHz, measured with the microstrip differential phase length method. RO3003G2 laminates have very low insertion loss of 1.3 dB/in. for 5 mil laminates, measured with the microstrip differential phase length method.
Dielectric constant variation throughout PCB processing is lower because of the homogeneous construction and the use of VLP ED foil. The RO3003G2 enables circuit designs with smaller diameter and denser micro vias, achieved by an advanced filler system using small rounded particles.
Rogers RO3003G2 high frequency PTFE laminates are available in
- Dielectric thicknesses of 0.005 and 0.01 in.
- Standard panel sizes of 24 in. × 18 in. (610 mm × 457 mm) and 24 in. × 21 in. (610 mm × 533.75 mm).
- 0.5 oz (18 µm) or 1 oz. (35 µm) ED Cu foil and rolled Cu foil.
The performance of the RO3003G2 high frequency PTFE laminates reflects Rogers long experience working with automotive radar customers to understand their increasingly stringent performance requirements.
