The RO3003 from Rogers Corporation is a Ceramic-filled PTFE based Laminate that can be used for RF & Microwave applications up to 40 GHz. The laminate has a dielectric constant of 3 (8-40 GHz) and provides exceptional plated through-hole reliability, even in severe thermal environments. It exhibits a coefficient of thermal expansion (CTE) of 17 ppm/degree C on the X and Y axis and 24 ppm/degree C on the Z-axis. This expansion coefficient is matched to that of copper, which allows the material to exhibit excellent dimensional stability, with typical etch shrinkage (after etch and bake) of less than 0.5 mils per inch.
The laminate is fabricated into printed circuit boards using the standard PTFE circuit board processing techniques and is suitable for use with epoxy glass multilayer board hybrid designs. It is ideal for global positioning satellite antennas, cellular telecommunications systems, power amplifiers and antennas, patch antenna for wireless communications, direct broadcast satellites, datalink on cable systems, remote meter readers, power backplanes, and automotive radar applications.
