New Antenna Level PCB Materials: RO4725JXR, RO4730JXR, and RO4730G3
Rogers launched the RO4725JXR, RO4730JXR, and RO4730G3 antenna level PCB materials to meet current and future higher performance requirements in active antenna arrays, small base stations, 4G base transceivers, Internet der Dinge (IoT) devices, and emerging 5G wireless system applications.
Flame Retardant RO4730G3 Thermosetting Laminate Material
This flame retardant (UL 94V-0) RO4730G3 thermosetting laminate material is a derivative of Rogers’ long trusted and popular circuit material for base station antenna applications. It has a low dielectric constant of 3.0, which is preferred by antenna designers, and a z-direction dielectric constant deviation of ± 0.05 bei 10 GHz.
Specifications and Features of RO4725JXR, RO4730JXR, and RO4730G3
