MAX2831/MAX2832 19-0363; Rev 2; 3/11 EVAALVUAAILTAIOBNLEKIT 2.4GHz to 2.5GHz 802.11g/b RF Transceivers with Integrated PA General Description The MAX2831/MAX2832 direct conversion, zero-IF, RF transceivers are designed specifically for 2.4GHz to 2.5GHz 802.11g/b WLAN applications. The MAX2831 pletely integrates all circuitry required to implement the RF transceiver function, providing an RF power amplifier (PA), RF-to-baseband receive path, basebandto-RF transmit path, VCO, frequency synthesizer, crystal oscillator, and baseband/control interface. The MAX2832 integrates the same functional blocks except for the PA. Both devices include a fast-settling sigma-delta RF synthesizer with smaller than 20Hz frequency steps and a digitally tuned crystal oscillator allowing use of a low-cost crystal. The devices also integrate on-chip DC-offset cancellation and I/Q errors and carrier leakage-detection circuits. Only an RF bandpass filter (BPF), crystal, RF switch, and a small number of passive ponents are needed to form a plete 802.11g/b WLAN RF frontend solution. The MAX2831/MAX2832 pletely eliminate the need for an external SAW filter by implementing on-chip monolithic filters for both the receiver and transmitter. The baseband filters are optimized to meet the IEEE 802.11g standard and proprietary turbo modes up to 40MHz channel bandwidth. These devices are suitable for the full range of 802.11g OFDM data rates (6Mbps to 54Mbps) and 802.11b QPSK and CCK data rates (1Mbps to 11Mbps). The ICs are available in a small, 48-pin TQFN package measuring only 7mm x 7mm x 0.8mm.
