Tips of how to start with RF?

I did post the ame post on the Analog forum but i jut realized that posting here is the bet option hehe:

Hi, i got some experience (not big) with analog filter design and signal conditioning for medical applications but i want to get into the RF world. Any one can give me any good reference for real applications? I am not looking for a real teorical material, but a more applyed one. For now, my analog knowledge is restricted to what i described and to what i learned on university with my sedra&smith book. I got some minimum experience with frequency domain but more related to transmission line applications and the basics of differential equation solving. I am really interested on high frequency RF applyed to radars but not a specific topology (UWB, dopple, and so on)

Thank you!

You can start with "RF Circuit Design" by Chris Bowick. It's a good book for RF beginners.
