LTSpice models for Analog Devices RF Detection

I recently watched a webcast (1/30/2019) on Analog Devices line of RF Detector IC's.   Was delighted to see that LTSpice models of some of these devices and inclusion in LTSpice (on page 29 of the slide deck) but am unable to find them in the very latest copy of LTSpice (version VII) or on the web site. As a longtime user of LTSpice, very interested in getting some of these models and putting them to work.  So anyone know where and how I can get them?
