Matériel de circuit à haute fréquence de carte PCB de Rogers ro3006
Rogers ro3006 is a PTFE composite with ceramic filler designed for high-frequency applications. This material offers exceptional temperature stability and mechanical reliability, making it suitable for a wide range of commercial microwave and RF circuits.
Dielectric Constant Stability
The dielectric constant of Rogers ro3006 exhibits high temperature stability, with a thermal stability coefficient (z direction) of -3ppm/°C between -50°C and +150°C at 10 GHz. The material also maintains high frequency stability, ensuring consistent performance across broad frequency ranges. At room temperature, there is no step change in the dielectric constant, providing reliable electrical properties.
Faible perte diélectrique
Rogers ro3006 demonstrates very low dielectric loss, measured at 0.0013 à 10 GHz, which is crucial for maintaining signal integrity in high-frequency applications.
Thermal Expansion Coefficient
Thanks to its composite nature, Rogers ro3006 has a thermal expansion coefficient in the X and Y directions of 17ppm/°C, equivalent to that of copper. This results in minimal etching shrinkage (less than 0.5mil/inch), ensuring excellent dimensional stability even in harsh environments up to 25ppm/Z.
Applications
With its superior electrical and mechanical stability, Rogers ro3006 is ideal for various commercial microwave and RF circuits, including automotive radar, GPS satellite antennas, amplificateurs de puissance, cellular communication system antennas, live satellite data links, cable system data links, remote meter reading devices, and power backplanes.
Rogers ro3000 Family of PTFE Ceramics
The Rogers ro3000 family comprises several PTFE ceramic variants, including ro3003, ro3010, and ro3035, each with different dielectric constants ranging from 3.0 à 10.2. Despite these variations, they share uniform mechanical stability, preventing warping or reliability issues when used in multilayer circuit designs.
