RO4730G3 High Frequency PCB 2-Layer Rogers 4730 20mil 0.508mm Printed Circuit
Board DK3.0 DF 0.0028 Microwave PCB
The RO4730G3 materials have a dielectric constant of 3.0 and a loss tangent 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 demonstrated low PIM performance, with
values better than -160dBc.
RO4730G3 materials are compatible with
conventional epoxy and high temperature lead-free solder processing. It does
not require the special treatment needed on traditional PTFE-based laminates for plated through holes preparation. Multi-layer can be achieved using RO4450F
bondply at 175℃.
The resin systems of RO4730G3 are designed to provide the properties sought
after by antenna designers. The glass transition temperature exceeds 280oC,
leading to a low Z-axis CTE, excellent plated through holes reliability, and
lead free solder processability.
Typical application is cellular base station
antennas.
