RT/duroid 6202PR laminates offer superior electrical and mechanical properties essential in designing complex microwave structures which are mechanically reliable and electrically stable. Excellent dimensional stability (0.05 to 0.07 mils/inch) is achieved by the addition of limited woven glass reinforcement. This enables the manufacture of tight tolerance planar resistors. Applications particularly suited to the unique properties of RT/duroid 6202PR materials include flat and non-planar structures such as antennas and complex multi-layer circuits with inter-layer connections.
