AL2236

2.4GHz RF Transceiver
For 802.11b/g Applications


Product Overview

AL2236 is a highly integrated RF transceiver IC for 2.4 GHz 802.11b/g applications. It embeds all circuitry required to implement the RF subsystem, including the receiver with on-chip LNA, transmitter with on-chip PA, VCO, frequency synthesizer, channel filters and variable gain amplifiers in order to minimize the use of external components. A power-on calibration procedure is established to correct the TX DC offset and filters mismatch. AL2236 is housed in a 40-pin QFN package.
