Product Overview
GT1265 is reinforced with glass fiber cloth to improve mechanical property, because of its lower expansivity and stronger dielectric constant compared with the laminate of non-fiberglass, it is very suitable for the design of RF circuits. As a circuit material, mechanical properties, dielectric constant, dielectric loss relative to the temperature variation is very stable, and it is easy to be processed to the size and shape required for.
