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 baseband processing, supporting up to 150 Mbps for 20 MHz and 300 Mbps for 40 MHz channel operations respectively, and IEEE 802.11b/g data rates.

Overview

Data Sheet February 2010 AR9287 Single-Chip 2x2 MIMO MAC/BB/Radio with PCIE Interface for 802.11n 2.

Key Features

include signal detection, automatic gain control, frequency offset estimation, symbol timing, and channel estimation. The AR9287 MAC supports the 802.11 wireless MAC protocol, 802.11i security, receive and transmit filtering, error recovery, and quality of service (QoS). The AR9287 supports two simultaneous traffic streams using up to two integrated transmit chains and receive chains for high throughput and range performance. Transmit chains combine baseband in-phase (I) and quadrature (Q) signa.
