The Arlon PCB 25FR 4-Layer RF PCB is a premium choice for high-frequency applications requiring superior thermal stability and environmental compliance. Built with a controlled dielectric constant ($D_k$) of 3.58, this multilayer board minimises signal attenuation and cross-talk in complex antenna networks. It features a halogen-free, flame-retardant formulation that meets strict modern safety regulations without sacrificing electrical performance, making it indispensable for advanced telecommunications and radar systems.
Key Features of Arlon 25FR
