AR9287
Description
The Atheros AR9287 is a highly integrated single-chip solution for 2.4 GHz 802.11n-ready WLANs to enable high-performance 2x2 MIMO configurations for applications demanding robust link quality and maximum throughput and range. The AR9287 integrates a multiprotocol MAC, baseband processor, analog-todigital and digital-to-analog (ADC/DAC) converters, 2x2 MIMO radio transceiver including LNA, PA, and RF switch, and PCI Express interface in an all-CMOS device for low power and small form factor applications.
Key Features
- All-CMOS MIMO solution interoperable with IEEE 802.11b/g/n WLANs
- 2x2 MIMO technology improves effective throughput and range over existing 802.11b/g products
- Integrated LNAs, PAs, and RF switches eliminate the need for external front-end modules
- Supports spatial multiplexing, cyclic-delay diversity (CDD), and maximal ratio bining (MRC)
- 2.4 GHz WLAN MAC/BB processing
- BPSK, QPSK, 16 QAM, 64 QAM, DBPSK, DQPSK, and CCK modulation schemes
- Data rates of up to 150 Mbps for 20 MHz channels and 300 Mbps for 40 MHz channels
- Wireless multimedia enhancements for QoS
- 802.11e-compatible bursting
- Support for IEEE 802.11e, h, and i standards
