Abstract :
We detail a delta-sigma based system built to produce high-resolution analog waveforms at UHF. With bandwidths as large as 80 MHz and noise floors as low as -140 dBc/Hz, the generated waveforms show potential for use as LO and RF transmission waveforms in a UHF radar system. Finally, the waveform generator system is described as an ideal technology for use in a digital phased array radar.
