General Description
The Rogers RO4725JXR High Frequency PCB is an antenna-grade circuit board designed for high-performance RF applications. Built on Rogers RO4725JXR laminates, this PCB offers a cost-effective alternative to traditional PTFE-based materials while maintaining excellent electrical and thermal properties. With a dielectric constant (Dk) of 2.55 ± 0.05, low Z-axis coefficient of thermal expansion (CTE) of 25.6 ppm/°C, and a dissipation factor ranging from 0.0022 to 0.0026, the RO4725JXR PCB ensures reliable performance in demanding environments. It is fully compatible with conventional FR-4 and high-temperature lead-free solder processes, making it easy to integrate into existing designs.
