Re: RFIC and MMIC domain
To add some comment to sergio's one:
MMIC and RFIC have, in my opinion, a lot of overlap. Maybe, for historical reasons, people who works in these fields, come often from different background:
MMIC is more distributed circuit design, power match, S-parameter, GaAs and so Microwave designers...
RFIC is more complex design (lot of transistors), silicon, analog design techniques and so microelectronic designers...
But as I have said, there is a lot of overlap, that in my opinion will grow with time. So a good engineer should have both competences!
Correct me if I'm wrong.
