Rogers RO4725JXR Material Introduction
Rogers RO4725JXR Hydrocarbon / Ceramic / Woven Glass antenna grade laminates are a reliable, low-cost alternative to conventional PTFE-based laminates. The resin systems of RO4725JXR dielectric materials provide the necessary properties for ideal antenna performance. RO4725JXR antenna grade laminates are fully compatible with conventional FR-4 and high temperature lead-free solder processing.
These materials do not require the special treatment needed on traditional PTFE-based laminates for plated through-hole preparation. RO4725JXR laminates are an affordable alternative to conventional PTFE-based antenna materials, allowing for designers to optimize cost and performance. They have the mechanical and electrical properties that antenna designers need, with values that allow antenna designers to realize substantial gain values while minimizing signal loss.
