I looked at this chip some time ago for use as the LO in an HF receiver,
and I abandoned it concluding that the noise performance of the VCO is about
20 dB shy of the minimum you need for good HF receiver overload performance

Does attenuating the signal before injecting it into the mixer help
avoid this problem?
