Hello! I just started a new job with a project involving laser synchronization. The idea of my colleague is to use basically DMTD as a phase detector (RF 3 GHz, IF=10..20MHz), and then digitize the IF with ADCs. He is very worried about AM/PM conversion (he's looking for something like 0.1degree/dB at 3 GHz), and he told me that the best results were with high LO level mixers (he was testing double balanced mixers eval boards, I think from minicircuit). I had a look at the literature and I found a paper [1] that put an upperbound between AM/PM and OIP3. Therefore I am looking for triple balanced mixers or DBM with high IP3. My question is: in your experience is that all or there's something else?
Thanks! [1] M. J. W. Rodwell, D. M. Bloom and K. J.
