Hi,
To explore higher frequencies one could imagine a set of 4 identical mixers and a common LO source and appropriate filters. The microwave LO and Kerberos LO would not be synchronized but this should not matter as the influence of the microwave LO will be identical on the 4 channels. It will be seen just as a modulation of the signal. I suppose the most critical part would be to build identical filters so that they do not introduce phase variations from one to another.
