The product is a RF transceiver IC for 802.11a/b/g wireless radios.
The MAX2828 and MAX2829 are single‑chip RF transceiver ICs designed for OFDM 802.11 WLAN applications. The MAX2828 targets single‑band 802.11a (4.9 GHz‑5.875 GHz) while the MAX2829 supports dual‑band 802.11a/g (2.4 GHz‑2.5 GHz and 4.9 GHz‑5.875 GHz). Both devices integrate the complete RF front‑end except for the PA, RF switches, filters and baluns, and are offered in a 56‑pin thin QFN package.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, pin configurations, and performance specifications such as Rx sensitivity (‑75 dBm at 54 Mbps), Tx sideband suppression (‑46 dB/‑51 dB), and dynamic range (60 dB Rx RSSI). Ordering information, package drawings, and chip process details are also included.
