Relong’s RC300C is commercial microwave and RF laminate material designed with low dielectric constant and very low loss characteristics. This ceramic-filled, woven fiberglass reinforced PTFE composite material is use unique  chemistry formulation and processing to offer RF and Microwave designers an advantage for improving electrical properties and mechanical performances.RC300C provides a significant improvement in performance stability over the current product line and other traditional fluoropolymer-glass laminates.

　　RC300C is ideal Base Station Antenna and Base Station Power Amplifiers material for low loss and low PIM（-168 dBc）. Other key features include low water absorption, lowest Temperature Coefficient of Dielectric Constant (TCEr =-23ppm/°C) and very low CTExyz (9, 15 and 50ppm/°C), high copper peel strength and good dimensional and thermal stability. It's Dielectric Constant 3.0 and tighter DK tolerance (±0.05) is desired for achieving high antenna efficiency and large bandwidth, and also provides a small degree of miniaturization that is critical to the size constraints of some antenna designs.
