I looked at this chip some time ago for use as the LO in an HF receiver,

20 dB shy of the minimum you need for good HF receiver overload performance
('reciprocal mixing").

Are you refering to a strong signal acting as a local oscillator and
when mixed with the phase noise sidebands of the actual local
oscillator
producing results which fall into the IF being used?

The phase noise performance of the ADF4360-8 is listed as -120 dBc/Hz
at 100 kHz offset from carrier. The MAX2620 which I was also
considering
is listed as -110 dBc/Hz at 25 kHz offset from carrier. What did you
end up
using and what are the specs?
