Single-/Dual-Band 802.11a/b/g World-Band Transceiver ICs

The MAX2828/MAX2829 single-chip, RF transceiver ICs are designed specifically for OFDM 802.11 WLAN applications. 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 transceiver function, providing a fully integrated receive path, transmit path, VCO, frequency synthesizer, and baseband/ 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 complete 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 CK/DSSS), at receiver sensitivity levels up to 10dB better than 802.11a/g standards. The MAX2828/MAX2829 transceivers are available in the small 56-pin, exposed paddle thin QFN package.
