Another very interesting bit of technology. The combination of so much functionality into such a small part is a real touch-stone as to where things are heading.
A quick look at the antenna design to see if I could sort down the details and then some die-decap to analyze the silicon a bit. The RF section is especially interesting. In the video I call out a section as being an inductor… on second thought as I type this it might even be a transformer?
Amazing…
