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.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
