AL5100/AL5301 Worldwide Ultrawideband Chipset

Worldwide Ultra Wideband Chipset Covers Entire UWB Spectrum from 3.1–10.6 GHz

High Integration

Alereon’s highly integrated AL5000 Family of Worldwide Ultra Wideband (UWB) chipsets integrates the RF transceiver, BBP/MAC, and firmware/software, to implement a complete WiMedia Ultra Wideband (UWB) product that supports all protocol adaptation layers, including Certified Wireless USB device and IP based protocols. The Alereon AL5000 family covers all worldwide band groups 1, 3, 4, and 6 from 3.1–10.6 GHz and was designed for desktop and laptop PCs; after market hubs, adapters, and cards; and embedded devices including PC peripherals, mobile handsets, and digital cameras, where space and power consumption are at a premium.

AL5100 RF Transceiver

The Alereon AL5100 transceiver integrates sensitive analog frontend components including synthesizer VCO/PLL, anti-alias filters, LNAs, PAs, and transmit/receive (T/R) switches, and supports a single-ended connection to the antenna eliminating external baluns. When combined with the Alereon AL5301 BBP/MAC, the AL5100 RF transceiver supports all current mandatory WiMedia specifications for worldwide band groups 1, 3, 4, and 6, including all TFCs 1–10.


The Alereon AL5301 BBP/MAC integrates all digital and mixed signal circuitry for a WiMedia UWB system providing high-speed wireless connectivity using either Wireless USB or IP-based WiMedia Link Layer Protocol. The AL5301 BBP/MAC uses a low power, highly efficient RISC processor combined with high precision hardware timers and specialized hardware for accelerating encryption, packet processing, and memory management. A programmable flexible host interface supports any one of multiple industry standards.


Alereon’s firmware/software partitioning minimizes the memory and processing demands on the host application. Wireless USB software drivers are available for PC operating systems including Windows XP/Vista/Windows 7 and Linux, and popular embedded O/S including Windows CE/WM5.0, Linux, MAC OS and Android. Alereon's NoWire™ driverless firmware may be selected for true out-of-the-box plug and play applications.
