Andrey Sviyazov andreysviyaz at gmail.comThank you Robin for hint. This is serious reason to use ADF. I think that a bit possible 2..3dB difference in noises at 0.6MHz ofset isn't big advantage. Other hand, I see that HMC has twice lower VCO sensitivity and better noises of dividers and than a seems a bit better. So, I'll try to design both variants on time and then will see.
