Introduction
Radio frequency (RF) can be a complex subject to navigate, but it does not have to be. If you are just getting
started with radios or maybe you cannot find that old reference book about antenna aperture, this guide can help.
It is intended to provide a basic understanding of RF technology, as well act as a quick reference for those who
“know their stuff” but may be looking to brush up on that one niche term that they never quite understood. This
document is also a useful reference for Maxim’s products and data sheets, an index to deeper analysis found in our
application notes, and a general reference for all things RF.
