Datasheet for Qualcomm Atheros AR9390

Single-chip, 2.4/5 GHz, 3-stream 802.11a/b/g/n solution with SST3 Technology for Enterprise WLAN

Product Overview
AR9390 is the single-chip, dual-band (2.4/5 GHz), 3-stream 11n solution with PCIe interface. It packs the breakthrough Signal-Sustain Technology 3 (SST3) technology that enhances the rate-over-range (RoR) performance. SST3 is a set of advanced technologies and features enabled by 802.11n including LDPC, TxBF and MLD. The end result is an impressive increase in rate-over-range of ~+100% at short range, ~+50% at mid range and ~+25% at long range.
To reduce the manufacturing cost, the AR9390 has successfully integrated external components such as the 2.4/5 GHz LNA and PA, switching regulators and EEPROMs. It has dramatically reduced the RBOM and has made the board manufacturing easy and simple.
Despite its mighty performance and high degree of integration, AR9390 consumes even less power in every operation mode – active TX, active RX, idle associated and sleep. It conserves energy while providing TCP throughput of more than 300 Mbps when used in 3x3 mode.
AR9390 has many unique features to support enterprise-grade WLAN applications, including full packet rate for 90-byte packets, loopback mode for FIPS certification, 4.9 GHz and 5/10 MHz channels, higher resolution for Spectral Analysis, Fast Channel Switch, and support for TDOA based locationing etc.
An Industrial Temperature (-40° C to 105° C) version of AR9390 is also available for outdoor and warehouse applications.
