Resources that describe the operation and design of individual RF components such as amplifiers, mixers, etc.
This article describes the mathematical basis for tradeoffs among noise figure, gain and return loss of an LNA, with implementation in an EDA design tool
This interactive demo allows you to experiment with waves and reflections under various conditions. The demonstration shows mechanical waves but the concepts are analogous to EM waves on transmission lines.
Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.
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.
Short tutorial on various balun designs.
The only easy-to-understand guide to the wireless revolution...
Use this handy Smith Chart web app to create matching networks. Easiest tool to use: drag elements right on the chart! Supports multiple frequencies, transmission line elements, etc.
Online Smith Chart course now available at Udemy.
Pozar's new edition of Microwave Engineering includes more material on active circuits, noise, nonlinear effects, and wireless systems. Chapters on noise and nonlinear distortion, and active devices have been added along with the coverage of noise and more material on intermodulation distortion and related nonlinear effects. On active devices, there's more updated material on bipolar junction and field effect transistors.
It's Back! New chapters, examples, and insights; all infused with the timeless concepts and theories that have helped RF engineers for the past 25 years! RF circuit design is now more important than ever as we find ourselves in an increasingly wireless world. Radio is the backbone of today's wireless industry with protocols such as Bluetooth, Wi-Fi, WiMax, and ZigBee. Most, if not all, mobile devices have an RF component and this book tells the reader how to design and integrate that component in a very practical fashion.
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.
Although this video is from 1959, it still provides and excellent explanation of wave properties and reflections.
