RO4730G3 UL 94 V-0 antenna-grade laminates meet performance requirements in active antenna arrays and small cells, notably in 4G base transceiver stations (BTS) and Internet of Things (IoT) applications as well as emerging 5G wireless systems. Flame-retardant (per UL 94V-0), thermoset laminates have dielectric constant (Dk) of 3.0, held to a tolerance of ±0.05 through the thickness (z axis) when measured at 10GHz. Are comprised of ceramic hydrocarbon materials with novel low-loss copper foil. Offer passive-intermodulation (PIM) performance better than -160 dBc typical, are 30% lighter than PTFE circuit materials, and feature a glass transition temperature (Tg) of better than +280°C for compatibility with automated assembly techniques. Z-axis coefficient of thermal expansion (CTE) of 30.3 ppm/°C from -55° to +288°C. Lead-free-process compatible. Dissipation factor of 0.0023 at 2.5GHz and 0.0029 at 10GHz.
