Direct synthesis of WiMedia UWB signals
Sep 1, 2007
By Iqbal Bawa, K. A. Muralidharan and Joan Mercade Although UWB promises high data rates, creating these signals in the lab and preserving their signal integrity is a highly complex process. One unique method of creating UWB-WiMedia signals uses an arbitrary waveform generator (AWG), yet retains the simplicity of using a dedicated UWB chipset. RF design engineers who use this unique method of AWG-based WiMedia signal generation will have several options, including IQ-baseband, IF and direct-RF-synthesis signal-generation techniques....
