Agreed, seems doable. Filtering plus amplification should fit in a suitable footprint pretty easily. Two channels of IQ upconversion would also probably be good, but most likely the upconverting mixer would need to have larger RF bandwidth than is typically available in surface mount IQ modules (which typically go to ~ 6 GHz spec'ed max, might be rough making it out to 12 GHz for Yb). Since we have full IQ control in the digital regime, we could do everything we want with just a regular mixer as long as filters are put in place to get rid of the second sideband on the output (these could be placed off-card as well, for example). The bandwidth of the DACs is sufficiently high that this method for removing the second sideband is viable, as long as appropriate filters are placed in the IF signal path. Just another potential way of generating things. _______________________________________________ ARTIQ mailing list https://ssl.serverraum.org/lists/listinfo/artiq
