Rogers RO3000 Series Dielectric Constant High Frequency Circuit Materials

  • June 21. 2022
Rogers RO3000 Series Dielectric Constant High Frequency Circuit Materials

RO3000 series circuit board material models: RO3003, RO3006, RO3010 and RO3035 high frequency laminate
RO3000 high frequency circuit material is a ceramic filled PTFE composite for commercial microwave and RF circuits.

RO3000 family of products is a circuit board material with electrical characteristics and mechanical stability and competitive price. RO3000 series laminates are based on ceramic filled PTFE circuit materials. The mechanical properties of the series plates with different dielectric constants are consistent. It is convenient for designers to use materials with different dielectric constants in a single layer circuit without warping or reliability problems when designing multilayer circuits.

The thermal expansion coefficient of RO3000 material in X and Y directions is 17ppm/℃. This value is comparable to the thermal expansion coefficient of copper, and the material typically exhibits dimensional stability due to etching shrinkage (etching after baking) of less than 0.5mils/inch. The CTE in the Z direction is 24 PPM /℃, which ensures the stability of electroplated holes even under severe temperature conditions. The dielectric constants of RO3003 and RO3035 materials are also very stable with temperature change.

Typical applications:
1- Vehicle radar
2- Global Positioning System satellite antenna
3- Cellular communication systems - amplifiers and antennas
4- Patch antenna for wireless communication
5- Live broadcasting satellite
6- Data links for wired systems
7- Remote meter reading
8- PSU backplane
