The RO3000® series laminates are high-frequency circuit materials designed for RF and microwave applications. These laminates are composed of ceramic-filled PTFE composites, offering excellent dielectric properties, thermal stability, and ease of fabrication.
2. Key Features
Low Dielectric Loss: Ensures minimal signal attenuation for high-frequency applications.
Stable Dielectric Constant (Dk): Available in a range of values (3.00 to 10.2) for diverse circuit requirements.
Thermal Reliability: High glass transition temperature (Tg) and low coefficient of thermal expansion (CTE) ensure stability during thermal cycling.
Compatibility: Suitable for hybrid designs with other materials and compatible with standard PCB fabrication processes.
