Abstract: An apparatus, including: an oscillator configured to generate a clock signal; a clock signal synthesizer configured to generate a first clock signal, a second clock signal, and a third clock signal, wherein the first, second, and third clock signals are based on the clock signal; a baseband transmitter configured to generate a transmit baseband digital signal in response to the first clock signal; an ultra-wideband (UWB) pulse digital-to-analog converter (DAC) configured to generate a UWB pulse signal based on the transmit baseband digital signal in response to the second clock signal; and a frequency upconverter configured to frequency upconvert the UWB pulse signal to generate a transmit radio frequency (RF) signal based on the third clock signal.
