Why Use WL-CT440 Instead of FR4 or PTFE for 2-Layer RF PCBs?
- May 19. 2026
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 ca...

How Does F4BTMS1000 PCB Compare to Global High-Dielectric Substrates? Introduction In the competitive landscape of high-frequency electronics, the choice of PCB substrate material directly determines the performance, reliability, and cost-effectiveness of the final product. For applications requiring high dielectric constant (Dk) values—such as phased array antennas, satellite communication...
