Product Overview - Decawave
www.decawave.comDW3000 is a fully integrated low-power, single chip CMOS RF 6.5GHz-8GHz IR-UWB transceiver IC compliant with the IEEE 802.15.4-2015 (HRP UWB PHY), IEEE 802.15.4z and IEEE 802.15.8 standards. DW3000 consists of an analog front end containing a receiver and a transmitter and a digital back end that interfaces to an off-chip host processor.

An inefficient antenna produces a small-amplitude EM wave for the same feed power, and converts most of the power into heat. Generally people don't think of radio-frequency radiation in terms of discrete particles (oscillating electrons and photons) -they typically use the wave

From his perspective your signal quickly drifts out of his passband. His digital readout is calibrated to
