I almost forgot I had this series of Microwave and RF Design books by Michael Steer at NC State University which are also officially available for free here: repository.lib.ncsu.edu/items/c920fb47…

Finally I found some time to open the thinkRF 28GHZ downconverter. Will post a teardown write-up later (analysis of the various sections, signal path, main components etc) Btw, my last 3 RF quizzes were from this board.

Is it really possible to draw the inductor of a DC-DC buck converter directly on the PCB? 🤔 So I just found this Semtech SC221 (so called X-EMI technology) operates at 20MHz The demo uses two anti-phase PCB inductors cancel magnetic fields and lower the EMI.

Acronyms list in my thesis... didn’t realize there were that many🤣
