Website

Everything RF is a product-focused website intended to help users find RF components more easily.

RF Globalnet is a product-focused website that helps simplify your search for RF components. You can also view white papers and app notes organized by industry segment.

A collection calculators, such as:

• Wave propagation calculation tool (for free-space and 2 wave model)
• Fresnel zone calculation tool
• Okumura-Hata curve calculation tool
• Creating a channel plan in order to avoid third-order intermodulation interference and the near-far problem tool
• Height pattern calculation tool
• Mutual conversion of decibel value and true value

Web apps are utilized in the tutorials to allow you to experiment with the concepts

This website features a comprehensive glossary of RF and Microwave terms along with many "rules of thumb" practical articles. It is now affiliated with the IEEE Microwave Theory and Techniques society.

This site is full of well-written tutorials on wireless communications and DSP topics.

Website with resources for DSP including materials from instructor Rick Lyons.

Antennas and Antenna Theory has always been a fascinating subject for me, and it is this excitement that leads me to present this tutorial. In my life, I have found that once I thoroughly understand a subject, I am amazed at how simple it seems, despite the initial complexity. This I have found true for a wide range of activities, be it riding a motorcycle, learning about antennas, or understanding physical phenomena such as electromagnetics. With that in mind, I endeavor to write this Antenna Theory website in the simplest of all possible manners.

Website with tutorials explaining Maxwell's Equations. It's also a great review if you have been out of school for a while.

This site aims to teach Maxwell's Equations in as simple and intuitive a manner as possible. This tutorial should be useful for anyone with an interest in electromagnetics. Don't fear the math - I'll explain that as well, while avoiding unnecessary rigor wherever possible.

This site is an archive of older application materials from Hewlett Packard. Information includes seminar notes, application notes, magazines, and more. Although the content is older, much of it is useful for understanding fundamental concepts related to RF and microwave.

A busy, often humorous site filled with information for RF and wireless engineers and technicians.

RF Cafe is a unique portal of RF, microwave, wireless, and other engineering resources. Vast collection of equations, references and conversions for electrical, mechanical, physical, and mathematical fields. Links for vendors, app notes, test notes, ham radio, magazines, books, active forums, patent and communications standards, technical crossword puzzles, quizzes, and much more.
