Product Details

Rogers RO4730G3 RF Printed Circuit Board 2-Layer Rogers 4730 60mil 1.524mm Microwave PCB with Immersion Tin

(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)

 

Rogers RO4730G3 antenna grade laminates are reliable, low-cost alternative to the conventional PTFE-based laminates. It has the mechanical and electrical properties that antenna designers need. The 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.
