DNMA-91: 802.11n b/g wifi 2x2 mini-PCI module, MB91/AR9223

DNMA-91 is an 802.11n b/g wifi 2x2 mini-PCI module designed specifically for cost-effective 2.4GHz integration on DSL motherboards, easing carrier manufacturer's design cycles to accelerate time-to-market that demand robust link quality and maximum price/performance ratio. Setting new standards in price/performance ratio, range, reliability, and power consumption, DNMA-91delivers the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.
Atheros AR9223 single-chip and 2 antennas design supports 2 simultaneous traffic MIMO streams using up to 2 integrated Tx and Rx assuring a higher quality experience to enhance user’s satisfaction.

 

Key Features

  • Mini-PCI Type-III A form factor in 2Tx/2Rx design is ideal for embedding into new or existing ergonomic devices.
  • Windows 2000/XP/Vista and Linux drivers enable manufacturers to quickly and easily bring new bandwidth intensive applications to market with trouble-free WiFi integration.
  • RF ESD and Surge protection up to 10KV ensure highest levels of performance and reliability in the harshest outdoor mesh/military deployments.
  • 802.11n compliance effectively interoperates with other chipsets.
  • Enables bandwidth of up to 300Mbps link rate for 40MHz channel, six times the throughput of 802.11g.
  • Supports IEEE 802.11b/802.11g backward compatibility allowing inter-operability among multiple wifi networks.
  • XSPANTM with Signal-Sustain Technology (SST) 2Tx/2Rx design architecture optimizes for higher and greater reliable throughputs over range.
  • Two Hirose U.FL antenna connectors support MIMO functionality.
  • One screw hole design to firmly assemble with main board.
  • RoHS 2002/95/EC compliance meets environment-friendly requirement.

Higher Performance than MB91 Reference Design:

  • 2.5dB Tx linearity improvement than standard MB91 design at 54Mbps.
