DNXA-97: 802.11n b/g wifi 2x2 PCIe half-size mini card, HB97/AR9287

 

DNXA-97 is a 802.11n b/g 2T2R in the smallest half-size mini card with PCIe form factor. AR9287 single chip solution integrates the MAC/baseband and radio transceiver, two enhanced MIMO power amplifiers and low noise amplifiers, and the transmit/receive switch, which leverages the 802.11n 2–stream specification to provide the optimal balance of performance from legacy 802.11 and 11n 1-stream solutions at comparable price point.

Setting new standards in throughput, range, reliability, and power consumption, DNXA-97 is capable to deliver the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.

 

Key Features

  • The smallest half-size mini card with PCIe form factor in 2Tx/2Rx design is ideal for embedding into ultra-compact devices or embedding additional mini cards with complimentary technologies at comparable price points.
  • Windows XP/Vista/7 and ath9k drivers enable manufacturers to quickly and easily bring new bandwidth intensive applications to market with trouble-free WiFi integration.
  • Atheros Linux SDK sub-license available by project.
  • Backward compatible to 802.11g and forward compatible to 802.11n provide the optimal upgrade path from legacy 802.11g and 802.11n 1-stream solutions. 
  • Up to 300Mbps PHY rate capability reduces congestion and increases capacity for additional wireless devices.
  • Advanced radio design techniques effectively double the wireless coverage over legacy WLAN.
  • Compliant with IEEE 802.11b, 802.11d, 802.11e, 802.11g standards and 802.11i draft specification 
  • RoHS compliance meets environment-friendly requirement.
