1. Introduction
This document describes about hardware specifications of “SX-PCEAC-DB”.
2. Overview
SX-PCEAC-DB is the radio module which supports Dual Band IEEE802.11ac/a/b/g/n and PCI express
1.1. This module complies with EU RoHS Directive 2011/65/EC(Lead Free). This module is made up
of an Chipset QCA9880-BR4A (Qualcomm Atheros) which contains a MAC/BBP, 2.4GHz RF front end
circuits and a 5GHz RF front end module AWL9581(Anadigics). Also this module supports high speed
3x3 SU-MIMO and 80MHz bandwidth.
Features
❑ IEEE 802.11ac/a/b/g/n conformity (2.4GHz & 5GHz)
❑ Supports the 3 streams 3 x 3 SU-MIMO system and 80MHz band width for 5GHz.
❑ Data rates of 1 - 54 Mbps for 802.11b/g, 6 - 54 Mbps for 802.11a, MCS0-7 for 802.11n and
❑ Supports IEEE802.11e, IEEE 802.11h and IEEE 802.11i.
❑ Supports PCI express 1.1 as the host IF of wireless LAN
* Not supported MU-MIMO and 160MHz bandwidth.
(Throughput up to 1300Mbps)
MCS0-9 for 802.11ac.

NOTE1
Antenna port. MHF4 type.
NOTE2
Stabilize +3.3VDC for RF.
NOTE2
Coverts +3.3VDC to +1.2VDC.
NOTE1
Any signals of 1 stream data, 2 stream data and 3 stream data is output from three antennas.
NOTE2
Any voltage source for RF parts are generated/stabilized on the module.(RF +3.3V, RF +1.2V)
RF performance shown in the product spec is not affected by any behaviors of external +3.3V supply.
