SPL218AW is a wideband active antenna splitter designed for multichannel RF distribution. It covers 470–890 MHz and delivers high linearity with an OIP3 of 38 dBm, enabling robust operation in the presence of strong interference. The internal amplifier compensates splitting losses and provides DC power through coaxial cable to supply Wisycom BAW high-power boosters (up to 700 mA at 12 V). It supports both AC and DC operation and includes fault indication.
