Flame retardant Hydrocarbon laminate for microstrip/stripline antenna

HF-300F is a flame retardant, ceramic-filled hydrocarbon-based copper clad laminate reinforced with woven fiberglass. The special ceramic-filled hydrocarbon composite offers low signal loss and superior, stable PIMD performance of -165 dBc in microwave antenna applications. HF-300F is well suited for hybrid multilayer applications. Emerging multilayer telecom applications put new demands on RF materials. HF-300F is dimensionally stable, has a low CTE, and is lightweight. HF300F's thermoset resin system offers advantages in PCB fabrication for large format, multilayer applications.
