Is there an RF focused equivalent to The Art of Electronics?
You will find that you need to use multiple books as the subject can be vast to learn depending on the area you want to work in. Older books tend to concentrate on valve technology such as Triodes, Tetrodes and Klystrons, while modern books concentrate on transistor technology (Bipolar and FET technology).
Chris Bowick book has already been mentioned, but below is my list of useful books and introductory books.
Experimental Methods in RF Design by Hayward, Campbell and Larkin.
RF Design Guide by Vizmuller.
Complete Wireless Design by Sayre
The Electronics of Radio by Rutledge
RF Design Basics by Fielding ZS5JF
More advanced books
High Speed Digital Design by Johnson and Graham
High Speed Signal Propagation
My tip is to get familiar with LCR networks using polar and rectangular form and biasing transistors at DC levels. Chris Bowick book is a good place to start but it does have the odd gap, but he has released a update version of his book, so those gaps may have been filled or edited out. My book is a brown cover which must be 20 year old now. Don't worry too much about the Smith Chart, Bowick book discusses the chart in reasonable detail.
