MAX2831ETM+ (MAXIM INTEGRATED PRODUCTS)

The MAX2831ETM+ is a 2.4GHz to 2.5GHz 802.11g/b RF transceiver with integrated PA in 48 pin TQFN package. It is a direct conversion, zero-IF, RF transceiver designed specifically for 2.4GHz to 2.5GHz 802.11g/b WLAN applications. It completely integrates all circuitry required to implement RF transceiver function, providing an RF power amplifier, RF to baseband receive path, baseband to RF transmit path, VCO, frequency synthesizer, crystal oscillator and baseband/control interface. It includes a fast-settling sigma-delta RF synthesizer with smaller than 20Hz frequency steps and a digitally tuned crystal oscillator. It integrates on-chip DC-offset cancellation and I/Q errors and carrier leakage-detection circuits. Only an RF band pass filter, crystal, RF switch & a small number of passive components are needed to form a complete 802.11g/b WLAN RF frontend solution. Suitable for the full range of 802.11g OFDM data rates (6Mbps to 54Mbps) & 802.11b QPSK & CCK data rates(1Mbps t
