RO4725JXR™ RO4730JXR™& RO4730G3™Antenna Grade Laminates Data Sheet
conventional PTFE-based laminates.
RO4725JXR™, RO4730JXR™ 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. 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 series 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.
