High-frequency electronic systems require PCB materials with lower dielectric loss and more stable impedance performance than standard FR4 can provide. In applications such as 5G communication, millimeter-wave radar, satellite communication, high-speed servers, and AI data processing equipment, PCB material selection directly affects signal integrity, transmission loss, and impedance control.
Rogers RO4350B hybrid high-frequency PCB boards combine RO4350B materials with FR4 layers in a hybrid stack-up structure. This design allows RF signal layers to benefit from the low-loss characteristics of RO4350B while using FR4 in non-critical layers to help control overall manufacturing cost.
With stable dielectric properties and low loss performance, RO4350B hybrid PCB structures are commonly used in RF circuits, antennas, radar modules, communication equipment, and other high-frequency applications that require reliable signal transmission.
