Artimi Inc. announced tape-out of what it claims to be the industry's first RF silicon to support both low band (3GHz to 5GHz) and high band (6GHz to 9GHz) operation, designed to be compliant with ultrawideband (UWB) regulations. The silicon supports WiMedia band groups 1, 3, 4 and 6, and FFI in the 4.2GHz to 4.8GHz. It has features to support detect-and-avoid operation in the 3GHz-5GHz band.

According to Artimi CEO Colin Macnab, the company's medium access control architecture is software configurable to support both the existing Certified Wireless USB standard and Bluetooth protocols on the same silicon. "This puts Artimi in a position to be first in providing complete system solutions to enable Certified Wireless USB and Bluetooth over WiMedia UWB. This capability will be compliant with global radio regulations and can also seamlessly coexist with mobile WiMAX and 3G/4G services."

Artimi's WiMedia-based semiconductor products are said to be suitable cable replacement for battery-operated handheld devices, such as digital still cameras, camcorders, MP3 players and cellphones. The products support data rates of up to 480Mbps and are said to be scaleable to 1Gbps and faster when the WiMedia standards evolve to support these data rates. According to Artimi, their architecture is firmware upgradeable to permit customization for future regulatory, standards and application requirements. The architecture and the WiMedia UWB common radio platform support other application protocols. In addition to Certified Wireless USB and Bluetooth over WiMedia UWB, Wireless 1394 and TCP/IP may reside on top of the WiMedia UWB platform.
