Hi, I want to know that the procedure of doing PCB layout of RF circuit board like what are the precautions will have to be taken to design high frequency circuit board and how this kind of circuit board is different from other normal board which operates on low frequency thank you.

 

Nothing like a post asking for an encyclopeic diseration! You will learn a lot by studying RF designs that have already been done. As for the basics, I think this article should get you started. There is much more to learn.
