57 GHz? What sort of parts are they using to get a consumer product BOM cost?

No idea what they are using but TI makes a bunch of parts that do radar in the MM wave band which is what that frequency is in. http://www.ti.com/sensors/mmwave/overview.html http://www.ti.com/sensors/mmwave/overview.html

  So I just looked up the prices on Mouser and Digikey for an amplifier or mixer in those frequencies, and boy are they expensive. The R&D spend must be enormous for them not to be making those parts in these frequencies as separate bits.

    I mean, you can make a RADAR with a single transistor, 2 diodes, an exotic but off the shelf VCO, and clever transmission lines. I doubt the R&D cost is very high for for the MMIC here.

    TI is making a 60 GHz RADAR in a CMOS process. I’m sure R&D costs were heavy, but production will be cheap. https://www.eetimes.com/document.asp?doc_id=1333330 https://www.eetimes.com/document.asp?doc_id=1333330

It's a custom-built chip according to https://atap.google.com/soli/ https://atap.google.com/soli/

They are working with Infineon, https://www.infineon.com/cms/en/product/promopages/soli/ https://www.infineon.com/cms/en/product/promopages/soli/ Infineon has a 24Ghz demo board for $150, https://www.mouser.com/ProductDetail/Infineon-Technologies/DEMOSENSE2GOLTOBO1?qs=rU5fayqh%252bE1u6j6iJNnMAA%3d%3d https://www.mouser.com/ProductDetail/Infineon-Technologies/D... & https://www.infineon.com/cms/en/product/sensor/radar-sensor-ics/24ghz-radar/ https://www.infineon.com/cms/en/product/sensor/radar-sensor-...

  Screw Infineon. They won’t provide the data sheet for their 80 GHz chipset, despite my buying $5k worth through their distributor.

    Infineon support is truely world-class awful. I’m looking at 100k with them this year and can’t get an answer to any technical question in any time frame. I probably wouldn’t select them again.
