802.11ac/n/a single band 3x3 PCIe mini card, QCA9880
Model: DAXA-O1
DAXA-O1 is a 3x3 802.11ac/n/a wifi module in standard PCIe mini card form factor designed to
deliver up to 1.3Gbps wireless data rates and target next-generation dual-band, dual-concurrent
(DBDC) home and enterprise wireless access points for a variety of high-reliable and bandwidth-
intensive video-over-wireless applications.
Unique Front End Module design allows co-located 5GHz RF standing up to -3dBm power injection
from 2.4GHz to provide non-degraded Rx sensitivity on dual-band, dual-concurrent (DBDC)
implementation. A new, highly efficient architecture reduces processing requirements and power
consumption, while nearly tripling wireless performance of 802.11n 3x3, to enable broad adoption of
home and enterprise wireless networking.
Key Features:
▪ Unique Front End Module design allows co-located 5GHz RF standing up to -3dBm power injection from 2.4GHz to
provide non-degraded Rx sensitivity on dual-band, dual-concurrent (DBDC) implementation.
▪ Supports 20/40/80MHz channel and 256 QAM to maximize bandwidth efficiency.
▪ Single band 802.11ac/n/a supports 3Tx/3Rx to enables antenna port data rate up to 1.3Gbps.
▪ Standard 29.85(W) x 50.80(L) mm PCIe full-size mini card with mounting holes is ideal for embedding into
ultra-compact devices or embed additional mini cards with complementary technologies.
▪ Three U.FL antenna connectors enable design flexibility to utilize different transmit/receive chains to
communicate with different users.
▪ REACH SVHC 73 (2011/12/19) and RoHS compliance ensure a high level protection of human health and the
environment from risks that can be posed by chemicals.
Rx Sensitivity Co-existence with 2.4GHz Interference Tx Power:
Unique Front End Module design allows co-located 5GHz RF standing up to -3dBm power injection from 2.4GHz to
provide non-degraded Rx sensitivity on dual-band, dual-concurrent (DBDC) implementation.
