Yes, it is too broad. You should look at a school like Berkeley and look at their concentrations. Maybe RF isn’t important if you’re doing systems (unless you’re interested in RF).
RF is not a required course in most universities. Some don't even have it as an elective. Were you thinking of electromagnetics? RF is a very specific subfield.
That's true maybe because it became such a big and deeply complex field that it has no space in the basic curriculum?
One might think that it's historically closely tied with the development of the radio and the telephone, see Tesla, Eddison, Bell Labs.
The common wisdom about electromagnetics with regard to EMI and such things seems to be that it's pretty much black magic. Similar for inductor selection in SMPS design.
It's pretty much physics, so a good deal about radiation can be found in medical physics for example, which is simply a different course of study with electronics as a side show, and maybe better as consecutive program for sophomores.
