As far as RF/Analog IC text is concerned, Razavi and Lee write some great conceptual discussions. Anything from the ARRL is great as well, if you want to look into the perspective of experimental engineers. The textbooks that I noted above come from the perspectives of former design engineers. They can be treated like design cookbooks that are equipped with appropriate discussions that substantiate common design techniques. I hope that these help. For a more general text that approaches a breadth of topics, the Art of Electronics by Paul Horowitz is an absolute classic, and it is a must read for developing the fundamentals strongly.
