Looking for Space Grade DAC (preferably dual channel)  for QPSK modulator

Hi Team,

Is there any Space/military grade versions available for the AD9761 DAC? Currently, we are looking for high-reliability DAC in order to provide I and Q data to the QPSK modulator in order to achieve a data rate up to 20 MBPS.

If not, can you please suggest alternate part no. for the same? Dual Channel DAC would be preferred as they can provide I and Q data within the single chip.

Thank you very much for your time and kind consideration. 

Regards
