Product Overview
GT1220 laminate is a composite material of glass fiber cloth and PTFE, which is suitable for such aspects as the strip line and microwave circuit. It has the effects of low Dk and Df, which can be used above the KU band, and can provide faster signal transmission and higher signal/noise ratio. The plate is easier to be cut and processed into the size needed.
