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?

    Hello BobGroh,

    You probably need to update your LTspice. It may be called 'Sync Release' on the menu. Mine is showing LTspice XVII for a Win10 machine. 

    From the place Component dialog, select 'Special Functions'. There, you can scroll to see LTC5505-1, -2, LTC5507, and LTC5532. 

    For learning and educational purpose, the LTC5507 is a good model to start with. You can independently control the input DC blocking capacitor and the external peak-hold capacitor, to simulate the tradeoffs between RF input frequency range, response time, output ripple feedthrough, etc. 

    If running transient analysis, simulation may converge much faster for you if you check (enable ) the 'Startup' option on the command dot line. 

    • Hello, I am using LTspice XVII for OS X. I don't have LTC5507 in my library as well. If possible, can you upload the .asy file here? Or do you know where I can download the file? Thank you so much for helping me!
