Design of a transmitter for Ultra Wideband Radio

Ultra Wideband Radio (UWB) is an upcoming alternative for wireless communications. Since the Federal Communication Commission in the USA allowed UWB for unlicensed usage in April 2002, more and more companies have started developing UWB systems. The major difference with UWB compared to other RF systems is that UWB sends information with pulses instead of using a carrier wave. The technique is from the nineteenth century and was first developed by Heinrich Hertz (1857-1894), which led to transatlantic communications 1901. This Master thesis presents a proposal of a transmitter for Ultra Wideband Radio using multiple bands. The proposed transmitter is implemented on system level in Simulink, Matlab. The frequency generation in the transmitter is also implemented at component level in a 0.13 um IBM process. The thesis begins with an introduction of UWB theory and techniques. Acknowledgments I would especially like to thank my supervisor Pär Svalänge at Bluechip IC Design AB for all the technical ideas and knowledge he has given me. I am also grateful to my examiner Shaofang Gong at the University of Linköping, Campus Norrköping for support. I would also like to thank the rest of the staff at Bluechip for technical knowledge and support.
