Rogers RO4730G3 PCB: Advanced Laminates for High-Gain Antenna Applications

Rogers RO4730G3 laminates are a reliable and economical alternative to conventional PTFE-based materials, offering the mechanical and electrical properties critical for antenna design. With a dielectric constant of 3.0 and a loss tangent of 0.0022 at 2.5 GHz (using LoPro Reverse Treated EDC foil), these materials support high gain and low signal loss. RO4730G3 substrate also features exceptional low PIM performance, with values better than -160dBc.

Compatible with standard epoxy and lead-free solder processes, Rogers RO4730G3 PCB streamlines production by eliminating the need for specialized treatments. Its high glass transition temperature (>280°C) ensures low Z-axis CTE, robust plated through-hole reliability, and excellent solder processability.

Widely used in cellular base station antennas, RO4730G3 high frequency PCB is a versatile and high-performance solution for modern antenna systems.
