General Description

The MAX2828/MAX2829 single-chip, RF transceiver ICs

are designed specifically for OFDM 802.11 WLAN appli-

cations. The MAX2828 is designed for single-band

802.11a applications covering world-band frequencies

of 4.9GHz to 5.875GHz. The MAX2829 is designed for

dual-band 802.11a/g applications covering world-bands

of 2.4GHz to 2.5GHz and 4.9GHz to 5.875GHz. The ICs

include all circuitry required to implement the RF trans-

ceiver function, providing a fully integrated receive path,

transmit path, VCO, frequency synthesizer, and base-

band/control interface. Only the PA, RF switches, RF

bandpass filters (BPF), RF baluns, and a small number

of passive components are needed to form the com-

plete RF front-end solution.

Each IC completely eliminates the need for external SAW

filters by implementing on-chip monolithic filters for both

the receiver and transmitter. The baseband filtering and

the Rx/Tx signal paths are optimized to meet the

802.11a/g IEEE standards and cover the full range of the

required data rates (6, 9, 12, 18, 24, 36, 48, and 54Mbps

for OFDM; 1, 2, 5.5, and 11Mbps for CCK/DSSS), at

receiver sensitivity levels up to 10dB better than 802.11a/g

standards. The MAX2828/MAX2829 transceivers are avail-

able in the small 56-pin, exposed paddle thin QFN pack-

age.
