RF Transceiver by Maxim Integrated

Note : Your request will be directed to Maxim Integrated.

The MAX2829 from Maxim Integrated is a Dual-Band 802.11a/b/g Transceiver IC that operates from 2.4 to 2.5 GHz and 4.9 to 5.875 GHz. It supports 40 MHz of channel bandwidth and has been specifically designed for OFDM 802.11 WLAN applications. The IC incorporates all circuitry required to implement the RF transceiver function, providing a fully integrated receive path, transmit path, VCO, frequency synthesizer, and baseband/control interface. This device 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 MAX2829 has an Rx sensitivity of -75 dBm at 54 Mbps with receiver gain-control of 93 dB (802.11g)/97 dB (802.11a). The device includes programmable baseband lowpass filters with integrated PLL with a 3-Wire serial interface. It has a Tx sideband suppression of -46dB (802.11g)/-51dB (802.11a) and a Tx EVM of 1.5% (802.11g) and 2% (802.11a). The IC features an I/Q analog baseband interface for Tx and Rx. It supports both serial and parallel gain control and allows digital mode selection (Tx, Rx, Standby, and Power Down).

This IC is available in a 56-pin QFN package that measures 8 x 8 mm and is ideal for 2.4 GHz/5 GHz MIMO and smart antenna systems, 4.9 GHz public safety radios, and single-/dual-band 802.11a/b/g radios applications.
