DNUA-93: 802.11n b/g wifi 1x1 USB module, UB93/AR9271

DNUA-93 is an 802.11n b/g wifi 1x1 MIMO USB module designed specifically to provide enhanced WiFi performance and value for home gateways, set-top boxes, gaming consoles, printers, and variety of other embedded WiFi products that host processors not originally intended to support WiFi functions. DNUA-93’s AR9271 single-chip features a new architecture that integrates both a CPU and memory to run more of the WiFi function on-chip. The integrated CPU offloads the wireless processing overhead from the host appliance and enables consumer electronic devices to support WiFi functions seamlessly without change of original host processors.

 

Key Features

  • Integrated CPU and memory to run more of WiFi function on-chip to offload wireless processing overhead from the host appliance.
  • 48 x 15mm small dimension with standard USB connector is ideal for embedding into new ergonomic home gateways, set-top boxes, gaming consoles, printers, and variety of other embedded WiFi products.
  • 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.
  • 802.11n compliance effectively interoperates with other chipsets.
  • Enables bandwidth of up to 150Mbps link rate, three times the throughput of 802.11g.
  • Supports IEEE 802.11b/802.11g backward compatibility allowing inter-operability among multiple wifi networks.
  • Two Hirose U.FL antenna connectors support MIMO functionality.
  • RoHS compliance meets environment-friendly requirement.
