Spurious Reduction with Tunable Reference ...

Hi,

I'm working with the "HMC833" chip and I would like to implemet the function "Spurious Reduction with Tunable Reference" but I can not find the algorithm to be adopted.

On page 24 of datasheet "hmc833.pdf" in the chapter "1.4.2.3 Spurious Reduction with Tunable Reference" I read:

"Hittite apps-support can assist with the required algorithms for ultra-low spurious tunable reference applications."

How can I get this additional documentation ?

Thanks very much.
