RFIC!!!

As you said RF=Radio Frequencyand and IC=integrated Circuits.
RFIC is a RF circuit, integrated in silicon chip (integrated inductances, RF transformers...)
There are still a lot of RF circuits that can't be integrated due to the performances that must be achieved:
- in an RFIC the "parasitics" play an important role and sometimes stand in the way.
- because the RFIC in integrated on a chip it can't disipate much thermal power, thus you can't integrate high power RF circuits.
