How to run HMC701 frequency synthesizer?

Hello,

I am working with HMC701, I read datasheet, but I couldn't find any application note about how to set registers to be able to obtain some particular frequency. I am using external VCO. I tried to do it everything according datasheet, but I failed to get desired frequency. I am using SPI protocol to communicate with HMC701, it is working. Has anyone worked with this chip so far? Does anyone have some experience with it? Is there any application note about it? What registers and how should be changed in order to get desired frequency?

Thank you.

Best regards,

Jugoslav
