Megtron is Panasonic's family of low-loss laminates that have become the industry standard for high-speed digital designs. Megtron 4 (Dk 3.8, Df 0.005) handles 5-10 Gbps and costs about 1.5-2x FR-4. Megtron 6 (Dk 3.4 at 10 GHz, Df 0.003-0.004) dominates 10-25 Gbps applications including 5G infrastructure and high-speed networking, at roughly 3-4x FR-4 cost. Megtron 7 (Df 0.003 at 12 GHz) targets 25-56 Gbps with 30% lower loss than Megtron 6. Megtron 8 achieves industry-leading Df of 0.0012 at 10 GHz for 56-112 Gbps PAM4 and 800GbE. Unlike PTFE materials, Megtron processes like standard FR-4 and works in hybrid stackups. Specify Megtron 6 as your baseline for anything above 10 Gbps.
