The AR6003 is the third-generation Wi-Fi chip from Atheros optimized for the throughput, size, and energy efficiency needs of mobile and embedded devices. With its tiny footprint and energy-saving qualities, the AR6003 rounds out Atheros’ comprehensive Align® ecosystem of 1-stream 11n solutions, targeting smartphones, mobile gaming and portable CE devices. With increased data throughput capabilities offered by 11n, the AR6003 achieves industry leading throughput. The AR6003 features the lowest current consumption of any 11n mobile WLAN solution on the market today to significantly extend battery life, while supporting the power demands of transmitting large files. The AR6003 also employs the company’s on-chip Efficient Power Amplifier™ (EPA) technology to reduce the power typically consumed by internal PAs, while delivering the output power of an external PA. The result is an average receive current consumption at 11n rates that is 20 percent lower than that of the AR6002, previously the industry’s lowest power mobile WLAN solution.
