Basic RF for IT is designed for newer engineers who come from an IT or non-technical background and need some training on the theory and components involved in generating radio frequency signals, as well as the principals involved with respect to maintaining and optimizing operation. While not intended to be an in-depth electronics education, this course provides familiarization with the theory and math involved in RF generation, as well as practical applications of that theory. Each course will consist of four modules and can be viewed individually or taken sequentially. Modules will be discussion-based, with theory and references provided throughout.
Basic RF for IT Series Module 4 discusses amplifiers and basic troubleshooting. None of the previous sessions matter if we can’t make a little signal into a big signal, and fix it when it doesn’t work as planned. This session looks at various amplifier designs and discuss troubleshooting techniques for each – how you approach a Doherty tube amp will be different than how you troubleshoot a current day solid-state amplifier. There will be some discussion on amplifier classes, pros and cons of each and how to use measurements to determine if things are operating as they should.
The other three Basic RF for IT Series Modules are available on demand.
