current position:home - products - interconnect solution -rc series rc300e is ideal base station antenna and base station power amplifiers material for low loss and low pim（-162 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 2.94 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.
rc300e has very low tcer, which enables the antenna designs to maintain high antenna gain and performance over wider operating temperature ranges by minimizing resonance frequency shift and bandwidth roll off at the temperature swings.
rc300e is compatible with the processing used for standard ptfe based printed circuit board substrates. in addition, the low z-axis thermal expansion provided by the ceramic loading, will improve plated through-hole (pth) reliability compared to typical ptfe based laminates.
