As a greenhand in the field of RF, what should i do first and then?Any suggestion?

I begin to learn about RF not long before, by reading few books,RF Ciruit Design Theory and Application(Reinhold Ludwig),RF microelectronics(Razavi) and microwave engineer. I should i do now except reading the three handbooks, some more? Are there some forum or website about the RF ? Should i start to design and simulate some tiny projects now?

Hi,
Of course design a system is the best way to learn. Simulation is complementary and you must have a good simulator (ADS is one of them). For Maxwell equation solver the simulation is very important when you have to design an antenna because antenna are difficult to tune in the reality (i think about patch antennas for example). Now, designing a project depend on the tools you have.
Good work and simulations.

enough of reading .... do some practical like making receivers, amplifiers.. ADS is a good tool for RF!
