AR5002AP-2X Solution Highlights

• Supports two wireless networks, IEEE 802.11a and 802.11b/g, concurrently

• Connects with any 802.11wireless client

• Uses digital CMOS technology exclusively, minimizing power consumption and cost while maximizing reliability

• Highly integrated 3-chip set provides unprecedented level of integration, reducing the chip count for a complete dual-band access point or router from nine chips to three

• 2.4/5 GHz dual band Radio-on-a-Chip (RoC)

• 2.4 GHz Radio-on-a-Chip

• Wireless System-on-a-Chip (WiSoC), including integrated 32-bit MIPS R4000-class processor with dual multiprotocol MAC/baseband processing engines that support both RoCs

• Super AG® mode delivers up to 108 Mbps raw data rate with typical end user  throughput exceeding 60 Mbps

• Hardware encryption support for the Wi-Fi Protected Access (WPA) and IEEE 802.11i security specifications provides Advanced Encryption Standard (AES), Temporal Key Integrity Protocol (TKIP) and WEP without performance degradation

• Wireless Multimedia Enhancements Quality of Service support (QoS)

• Extended tuning range (2.300-2.500 & 4.900-5.850 GHz) for worldwide use

• Dynamic Frequency Selection/Transmit Power Control (DPS/TPC) for international operation

• Support for draft IEEE 802.11e, h and i standards

• Enhanced third generation performance, transmission range and reliability

The chipset includes:

AR5112 Dual band Radio-on-a-Chip (RoC) for 2.4/5 GHz WLAN

• All CMOS dual band radio chip
• Dynamic IF Dual Conversion architecture provides super-heterodyne performance at Zero IF prices
• Operates from 2.300 - 2.500 GHz and 4.900 - 5.850 GHz
• Integrated third-generation power amplifier (PA) and low-noise amplifier (LNA)
• External PA and/or LNA can be used for special applications
• Enhancements to the transmit and receive chains
• Eliminates all IF filters and most RF filters; no external voltage-controlled oscillators (VCOs) or surface acoustic wave (SAW) filters needed
