current position:home - products - high-frequency high-speed seri -rc seriesrelong’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.
