I am investigating the ADC/DAC power consumption vs. sampling rate in
different software defined radio’s. Where can I get the specific ADC and
DAC models that an USRP RF daughterboard (e.g. SBX) uses? If I know the
model, I assume that I can go to the manufacturer’s website and find the
power consumption model.

In general, is the ADC/DAC power consumption of the present-day SDR’s
comparable to the maximum transmit power (e.g. 100 mW in SBX)? If anyone
has looked at it before, please let me know.

Thanks for reading the email!

Current Ettus RF daughter cards work entirely with analog signals, DAC
and ADC are on the “Motherboard”.
You can look at the published schematics for the model(s) you are
interested to extract the part numbers.

As a general rule RF broadband converters working with sampling
frequencies in the hundreds of MHz consume power on the order of single
digit Watts.
