DHXA-222 fiche technique
802.11n a/b/g 2x2 wifi and Bluetooth 4.0 + HS combo PCIe half-mini card, WB222/AR9462
Model: DHXA-222
DHXA-222 is a single-chip solution that combines dual-band (2.4/5GHz) 2-stream
802.11n WiFi and Bluetooth 4.0 technology on a single half-size mini card in PCIe
form factor designed for notebooks, netbooks, and tablets. DHXA-222 brings
Atheros’ industry-leading dual-band 2x2 802.11n performance and latest Bluetooth
4.0 specification to increasingly smaller computing and CE devices. Dual-band 2x2
802.11n WiFi delivers data rate of 300 Mbps and TCP throughput of more than 200
Mbps in 2x2 mode. Unique Signal-Sustain Technology™ (SST) increases rate-over-
range performance by up to 100% at short range, 50% at mid-range, and 25%
at long range. Bluetooth 4.0 supports high speed and low energy operation, and
supports enhanced data rate (EDR) of both 2 Mbps (4-DQPSK) and 3 Mbps (8-DPSK).
Advanced integrated coexistence features deliver superior WiFi/Bluetooth coexistence
to ensure the best possible wireless experience, maximum performance, and lowest
power consumption.
Key Features:
▪ Dual-band (2.4/5GHz) 802.11n 2Tx/2Rx WiFi and Bluetooth 4.0 + HS combo solution on a single half-size mini
card in PCIe form factor is ideal for embedding into increasingly smaller computing and CE devices.
▪ Dual-band (2.4/5GHz) 2-stream 802.11n offers a maximum PHY rate of 300 Mbps.
▪ Using Dynamic MIMO power Save to conserve power with 1x1 downshift.
▪ Signal-Sustain Technology™ (SST) increases rate-over-range performance by up to 100% at short range, 50% at
mid-range, and 25% at long range.
▪ Bluetooth supports high speed and low energy operation
▪ Bluetooth supports enhanced data rate (EDR) of both 2 Mbps (4-DQPSK) and 3 Mbps (8-DPSK).
▪ Advanced integrated coexistence features deliver superior WiFi/Bluetooth coexistence to ensure the best possible
wireless experience, maximum performance, and lowest power consumption.
▪ Supports Fast Channel Switch (FCS) to reduce channel switching time to as little as 1ms within band and 2 ms in
between the 2.4GHz and 5GHz bands.
▪ Supports antenna sharing between Bluetooth and WLAN.
▪ Driver support for Windows XP/Vista/7 and Linux enables system integrators to quickly and easily employ multi-
radio coexistence on one platform with trouble-free WiFi and Bluetooth integration.
▪ RoHS compliance meets environment-friendly requirement.
