Product Description
In the design of complex microwave structures—from phased array antennas to airborne radar systems—material selection plays a decisive role in achieving reliable, repeatable performance. Rogers RT/duroid 6202 is a low-loss, low-dielectric-constant laminate with limited woven glass reinforcement, engineered to deliver the electrical and mechanical stability essential for demanding high-frequency applications.
RT/duroid 6202 is available with ½ oz. to 2 oz./ft² electrodeposited or rolled copper foil on dielectric thicknesses ranging from 0.005" to 0.060" (0.127 mm to 1.524 mm). Its excellent dimensional stability (0.05 to 0.07 mils/inch) often eliminates the need for double etching to achieve tight positional tolerances, simplifying fabrication and improving yield.

Low Loss for High-Frequency Performance:
RT/duroid 6202 offers a dissipation factor of just 0.0015 at 10 GHz, minimizing signal attenuation in transmission lines and ensuring excellent high-frequency performance across microwave and millimeter-wave bands.
Excellent Dimensional Stability:
With dimensional stability of 0.05 to 0.07 mils/inch—achieved through limited woven glass reinforcement—RT/duroid 6202 often eliminates double etching, reduces registration errors, and improves manufacturing yields for tight-tolerance designs.
Matched In-Plane Expansion:
The X- and Y-axis CTE of 15 ppm/°C is closely matched to copper, reducing stress on plated through-holes and improving reliability through thermal cycling. The low Z-axis CTE of 30 ppm/°C further enhances dimensional stability in multilayer constructions.
Low Thermal Coefficient of Dk:
At just 5 ppm/°C over -50 to +150°C, the dielectric constant remains highly stable across temperature, ensuring consistent electrical performance in environments subject to wide temperature swings.
Thermal and Moisture Resistance:
Very Low Etch Shrinkage:
The material exhibits very low etch shrinkage, contributing to precise feature definition and repeatable circuit performance.
