Definition

Rogers Corporation is a leading manufacturer of high-frequency PCB materials. Their product lines include RO4000 series (thermoset non-PTFE with FR-4 processing), RT/duroid (PTFE/woven glass and ceramic-filled), and TMM (thermoset ceramic-filled). When to choose Rogers: RF designs above 1-2 GHz where FR-4 loss and Dk variation degrade performance, antenna substrates requiring stable Dk, and high-power amplifiers needing thermal conductivity. RO4003C and RO4350B (Dk ~3.38-3.48) are popular up to 10 GHz. For higher frequencies into millimeter-wave, RT/duroid materials are typical. Rogers costs more than FR-4 but most digital designs below 10 Gbps can use standard FR-4 or mid-loss materials.
