In looking into extremely low phase noise synthesizers, I have come across the new HMC700LP4 chip from hittite, which seems to have the best figure of merit I have found, -227 dBm/Hz. That gives you -107dBc/Hz at 20 kHz offset at 6 GHz according to the datasheets.
That sounds amazingly good, but my R+S signal generator does better. Do they use a different sort of architecture? Do they not use conventional dividers? Some other sort of phase detector?
