CLTE-MW laminates are ceramic-filled, woven glass reinforced PTFE composites.
Are for applications that have limitations in thickness due to physical or electrical constraints. Seven thickness options from 3 mils to 10 mils reportedly ensure signal to ground spacing for 5G and other millimeter wave designs. Reinforced with spread glass. Woven glass reinforcement provides excellent dimensional stability. Other features include low z-axis CTE (30ppm/°C), loss tangent of 0.0015 at 10GHz, and moisture absorption of 0.03%. Thermal conductivity of 0.42W/(m.K) enables heat dissipation in aggressive designs, along with a dielectric strength of 630V/mil. UL94 V-0 flammability rating enables use in commercial applications. Suited for amplifiers, antennas, baluns, couplers and filters. Copper foil options are available, including rolled, reverse treated ED, and standard ED. Resistive foil and metal plate options also available.
