Abstract :
We describe a dual conversion, 3-5 GHz UWB pulse radio transmitter architecture using interleaved, IF digital-to-analog converters (DACs) followed by a partial-order hold reconstruction filters that eliminate sampling images, and an RF upconverter. 1.25 nJ is spent per pulse for a pulse-repetition rate (PRR) of 100 MHz while achieving a broadband image cancellation of 42 dBc.
