This is a WiFi radio chip which was pulled from a WiFi card which was inside the same laptop as the Turion CPU I imaged earlier.
This chip seems to be soldered to the metal plate which is present in most epoxy encased chips. I have not seen this before, normally thermal paste is used and I am able to detach this plate. This made the photography of this chip much more difficult due to the uneven surface on the back of this plate.
The small black square in the bottom left region has inscriptions of the broadcom logo, "BCM2050A1", "2002", and a repeated sequence of "1" characters.
I do not understand the purpose of the large circular structures, if anyone does please leave a comment below!
Update: A friend of mine thinks they may be inductors, and after some searching online I am quite confident he is right.
This is a composite of 54 images taken by a pixel 2XL from a microscope at 100X. The images had 65% overlap and were stitched together in Microsoft Image Composite Editor using the structured panorama mode.
