Why Use WL-CT440 Instead of FR4 or PTFE for 2-Layer RF PCBs? When designing a 2-layer PCB for high-frequency RF applications—such as phased array antennas, airborne radar, or satellite communications—the choice of dielectric material is arguably the most consequential decision after the schematic itself. At frequencies above 1 GHz, the PCB substrate ceases to be a passive mechanical carrier a...
