The AR6103 is a complete, small form factor 802.11 b/g/n Wi-Fi solution optimized for lowpower, low-cost, and highly integrated mobile and portable consumer electronic devices. The device integrates all Wi-Fi functionality in a package friendly to low-cost PCB design, requiring only a few external bypass capacitors and connection to an antenna. The AR6103 is part of the 3rd generation ROCm™ family of mobile 11n devices, employing the world’s lowest power consumption embedded architecture.

The AR6103 can support numerous external Bluetooth devices, and includes advanced PTA coexistence support. A flexible architecture enables optional customization to meet customer specific profiles and use cases. On-chip high-efficiency high-output EPA™ power amplifier with zero calibration, integrated LNAs, integrated receive and transmit RF matching circuits, integrated reference crystal, and integrated T/R switch eliminate the need for external RF components and enable direct antenna connection.  Block Diagram Ultra low power consumption radio architecture and proprietary power save technologies extend battery life. On-chip highefficiency PMU (power management unit) enables direct-connect to battery, eliminating the need for external regulators. An on-chip embedded CPU handles complete 11n processing to minimize host processor loading.
