DHXA-195: 802.11n b/g 1x1 wifi plus Bluetooth combo PCIe half-size mini card, WB195/AR9285+AR3011

DHXA-195 is the industry’s first 1-stream 802.11n WiFi plus Bluetooth v2.1 combo solution on a single half-size mini card with PCIe form factor. 

The WiFi part of DHXA-195 uses AR9285, which integrates the radio transceiver and the media access controller/baseband sections into a single chip along with the power amplifier, low-noise amplifiers, and antenna switch, can deliver 11n single stream (1x1 SISO) at data rate to 150 Mbps. The Bluetooth connectivity is implemented with AR3011 chip complying with the Bluetooth 2.1 + EDR (extended data rate) standard and upgradeable to Bluetooth 3.0.

DHXA-195 high-performance WiFi/Bluetooth coexistence schem allows faster Web surfing and file transfers, smooth media streams, and clear voice transmissions on the WiFi link, all with uninterrupted synching of wireless PC peripherals like mice and keyboard on the Bluetooth link. Windows XP/Vista/7 and Linux driver support enables ASD (Application Specific Device) manufacturers to quickly and easily employ multi-radio coexistence on one platform with trouble-free WiFi and Bluetooth integration.
