The STLC4420A is a single chip dual band WLAN solution for embedded, low-power, high performance and very small form factor mobile applications. The product conforms to the IEEE 802.11b, 802.11g and 802.11a protocols operating in the 2.4 GHz and 5 GHz frequency band, supporting OFDM data rates of 54, 48, 36, 24, 18, 12, 9, and 6Mbps in the both bands and CCK data rates of 11 and 5.5Mbps and legacy data rates of 2 and 1Mbps at 2.4 GHz. The STLC4420A is a fully integrated wireless radio including a ZIF transceiver, RF synthesizer/VCO, high-speed data converters, an OFDM/CCK digital baseband processor, an ARM9-based MAC and a complete power management unit with integrated PA bias control. An external dual band FEM completes a highly integrated chip set solution.
