Rogers RO4350B High Frequency Laminate China Suppliers and Factory
The Rogers RO4350B is a high-performance hydrocarbon ceramic laminate engineered specifically for high-frequency and microwave applications. By offering tightly controlled dielectric constants (Dk) and exceptionally low loss characteristics, it provides a superior alternative to traditional PTFE materials, enabling engineers to achieve precise signal integrity in demanding RF designs.
Unlike many specialized microwave laminates, RO4350B is designed for seamless integration with standard epoxy/glass processing methods. This eliminates the need for specialized through-hole processing, significantly reducing overall production costs while maintaining a UL 94 V-0 flame retardancy rating, making it an ideal choice for high-power RF designs and active device integration.
