TF600 PCB: When High-Frequency Designs Demand Ceramic-Filled PTFE
- April 29. 2026
TF600 PCB: When High-Frequency Designs Demand Ceramic-Filled PTFE In an age where every decibel of insertion loss and every degree of phase instability can determine the success of a wireless product, the choice of PCB material is no longer a secondary design decision. For RF and microwave engineers, FR-4 often becomes a bottleneck beyond 3 GHz—not because it fails outright, but because it ...

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 carrier a...
