Product Overview
GT1650 laminate is a composite material of special enforcement by glass fibre and added high dielectric special ceramics powder PTFE, which is suitable for wireless communications equipment antenna and so on. This type laminate is made of high-molecular polymer, easy to process, and it has excellent mechanical performance and good effect on the miniaturization of antenna, also it provides the required miniaturization for miniaturized antennas especially for microwave power dividers, power combiners, electronic amplifiers, filters, couplers and other components.
