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 RO4350B LoPro PCB Solve Conductor Loss Issues in High-Speed Electronics?   As electronic systems push toward millimeter-wave frequencies and data rates exceeding 100 Gbps, conductor loss has emerged as the single most critical bottleneck limiting performance. In 5G mmWave base stations, satellite communication payloads, and high-speed data center backplanes, even a 0.1 dB/inch increa...
