See Figure 1 for the architecture block diagram. Figure 1 Reference 1 architecture for the “all-digital” pulsed UWB transmitter. (Image courtesy of Reference 1) Not bad, but not my idea of a ...

In the direct modulation transmitter, an RF DAC is used and the cable channel is created entirely in the digital domain, typically an FPGA. The digital signal is sent from the FPGA to an RF DAC, where ...
