UWB PHY device combines RF, BB components in single chip

What is a semiconductor?
A class of materials, for instance silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber). It displays relatively high resistance in pure state and much lower resistance when it contains small amounts of certain impurities.

What is UWB technology?
Ultrawideband (UWB) is a technology for transmitting information over a large bandwidth (>500MHz) that should, in theory and under the right circumstances, be able to share spectrum with other users. UWB is ideally suited for streaming multimedia in the wireless home or office environment.
