Re: beginer in RF
Please be more specific what you want, general RF, discrete RF or RFIC?
For a beginner I'd suggest you start learning transmission line theory as this belongs to the very basics of RF. Then go on with multiport networks and S-parameters, then filters, and finally active RF circuits like mixers and oscillators. There are several books on this, and a quite good one is RF circuit design by Reinhold Ludwig.
What renwl suggested is a book on CMOS RFIC. Referring to old topics in RF, it looks like many people thinks that RF is exactly RFIC. I think RFIC belongs more to analog IC design. Anyway, I think the book by Lee isn't that good for RFIC either. I think Razavi's book is better, since it provides more details and thorough derivations. Then when you have experience with RFIC then you might want to swith over to Lee's book.
