Новые материалы печатных плат антенного уровня: RO4725JXR, RO4730JXR, and RO4730G3
Rogers launched the RO4725JXR, RO4730JXR, и материалы печатных плат антенного уровня RO4730G3 для удовлетворения текущих и будущих требований к более высоким характеристикам в активных антенных решетках., small base stations, 4G base transceivers, Интернет вещей (Интернет вещей) устройства, and emerging 5G wireless system applications.
Flame Retardant RO4730G3 Thermosetting Laminate Material
This flame retardant (UL 94V-0) RO4730G3 thermosetting laminate material is a derivative of Rogers’ long trusted and popular circuit material for base station antenna applications. It has a low dielectric constant of 3.0, which is preferred by antenna designers, and a z-direction dielectric constant deviation of ± 0.05 в 10 ГГц.
Specifications and Features of RO4725JXR, RO4730JXR, and RO4730G3
RO4730G3 Laminate Composition and Properties
