AR9287 Single-Chip 2x2 MIMO MAC/BB/Radio with PCIE Interface for 802.
11n 2.
4 GHz WLANs
General 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.
The AR9287 implements half-duplex OFDM, CCK, and DSSS ba...
