Silex Technology SX-PCEAC PCI Express Half Mini Card WLAN Modules are radio modules that support dual-band IEEE802.11ac/a/b/g/n and PCI express 1.1. These modules are made of chipset QCA9880-BR4A that contains a MAC/BBP 2.4GHz RF front end circuits and a 5GHz RF front end module 85717-11 (Skyworks). The SX-PCEAC PCI express half mini card WLAN modules feature 3 spatial data stream systems (3T3R) and offer 1.3Gbps maximum data transfer rate. These modules are designed with 3×3 SU-MIMO with wideband 80MHz mode and high-density modulation module. The SX-PCEAC PCI express half mini card WLAN modules are RoHS compliant and comply with EU RoHS directive 2011/65/EC (lead-free). These WLAN modules operate at the 0°C to 60°C temperature range and -0.3V to 3.6V supply voltage range.
