AR9220 Single-Chip 2x2 MIMO MAC/BB/Radio with PCI Interface for 802.11n 2.4 and 5 GHz WLANs
General Description
The Atheros AR9220 is a highly integrated single-chip solution for 2.4 and 5 GHz 802.11nready wireless local area networks (WLANs) that enables high-performance 2x2 MIMO configurations for wireless station applications demanding robust link quality and maximum throughput and range. The AR9220 integrates a multi-protocol MAC, baseband processor, analog-to-digital and digital-to-analog (ADC/ DAC) converters, 2x2 MIMO radio transceiver, and PCI interface in an all-CMOS device for low power and small form factor applications. The AR9220 implements half-duplex OFDM, CCK, and DSSS baseband processing, supporting up to 130 Mbps for 20 MHz and 300 Mbps for 40 MHz
