I found this page when searching for the ICs in (what I now know is) a tuner module. Surprised that this site has never been posted to HN before. I'm working on FMCW radar related stuff so it was super interesting to me too.

I found it sometime last year, looking for data on a Philips video IF processing chip, I thought about posting it. Great site from an interesting guy, a rather sad history of the decline of electronics manufacturing in western europe though, death by bean counters.

What was the IC you were looking for, PLL synthesizer or Demodulator?

I was just curious about the chips inside one of these tuner modules, so I searched up their label and went to images. The two things are TDA5737 and TSA5522, which seems to be mixer and synthesizer.
