EVALUATION KIT AVAILABLE MAX2828/MAX2829 Single-/Dual-Band 802.11a/b/g World-Band Transceiver ICs General Description Features World-Band Operation The MAX2828/MAX2829 single-chip, RF transceiver ICs MAX2828: 4.9GHz to 5.875GHz (802.11a) are designed specifically for OFDM 802.11 WLAN appli- MAX2829: 2.4GHz to 2.5GHz and 4.9GHz to cations. The MAX2828 is designed for single-band 5.875GHz (802.11a/b/g) 802.11a applications covering world-band frequencies of 4.9GHz to 5.875GHz. The MAX2829 is designed for Best-In-Class Transceiver Performance -75dBm Rx Sensitivity at 54Mbps (802.11g) dual-band 802.11a/g applications covering world-bands -46dB (802.11g)/-51dB (802.11a) Tx Sideband of 2.4GHz to 2.5GHz and 4.9GHz to 5.875GHz. The ICs Suppression include all circuitry required to implement the RF trans- 1.5% (802.11g) and 2% (802.11a) Tx EVM ceiver function, providing a fully integrated receive path, -100dBc/Hz (802.11g)/-95dBc/Hz (802.11a) transmit path, VCO, frequency synthesizer, and base- LO Phase Noise band/control interface. Only the PA, RF switches, RF Programmable Baseband Lowpass Filters bandpass filters (BPF), RF baluns, and a small number Integrated PLL with 3-Wire Serial Interface of passive components are needed to form the com- 93dB (802.11g)/97dB (802.11a) Receiver Gain- plete RF front-end solution. Control Range Each IC completely eliminates the need for external SAW 200ns Rx I/Q DC Settling 60dB Dynamic Range Rx RSSI filters by implementing on-chip monolithic filters for both 30dB Tx Power-Control Range the receiver and transmitter. The baseband filtering and Tx/Rx I/Q Error Detection the Rx/Tx signal paths are optimized to meet the I/Q Analog Baseband Interface for Tx and Rx 802.11a/g IEEE standards and cover the full range of the Digital Mode Selection (Tx, Rx, Standby, and required data rates (6, 9, 12, 18, 24, 36, 48, and 54Mbps Power Down) for OFDM 1, 2, 5.5, and 11Mbps for CCK/DSSS), at Supports Both Serial and Parallel Gain Control receiver sensitivity levels up to 10dB better than 802.11a/g MIMO and Smart Antenna Compatibility standards.
