Antenna Grade Laminates
RO4700™ series antenna grade laminates are a reliable, low-cost alternative to the
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.

rolonged exposure in an oxidative environment may cause changes to the dielectric properties of hydrocarbon based materials. The rate of change increases at higher temperatures and is highly dependent
on the circuit design. Although Rogers’ high frequency materials have been used successfully in innumerable applications and reports of oxidation resulting in performance problems are extremely rare, Rogers
recommends that the customer evaluate each material and design combination to determine fi tness for use over the entire life of the end product.
