RO4725JXR™ & RO4730G3™ Antenna Grade Laminates Data Sheet
RO4725JXR™ and RO4730G3(TM) laminates have the mechanical and electrical properties that antenna designers need. The laminates have a dielectric constant (Dk) of 2.55 and 3.0 and a loss tangent (Df ) of 0.0022 measured at 2.5 GHz when using LoPro® Reverse Treated EDC Foil. These values allow antenna designers to realize substantial gain values while minimizing signal loss. Materials are available with a demonstrated low PIM performance, with values better than -160 dBc (43dBm 1,900MHz signal). [2]
RO4700 series antenna grade laminates are compatible with conventional epoxy and high temperature lead-free solder processing. These laminates do not require the special treatment needed on traditional PTFE-based laminates for plated through hole preparation. Lamination can be achieved using RO4400™ bondply series at 175°C. The resin systems of RO4700JXR materials are designed to provide the properties sought after by antenna designers. The glass transition temperature exceeds 280°C (536°F), leading to a low Z-axis CTE, excellent plated through hole reliability, and lead-free solder processability.
