Specifications of MAX2829ETN+T

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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.
