We have created this online course for engineers, technicians, production, manufacturing, applications, and other professionals that require a firm foundation in the principles of RF and wireless technologies. A full overview of RF analytical tools, communications signals, RF devices, and test equipment. This module covers test instrumentation, RF components, and modulation after introducing fundamental analytical tools like the decibel scale, S-parameters, and the Smith Chart. The foundation of the course outline is a simple block diagram of a transmitter-receiver chain. I described the relative performance parameters for each component. We introduce key impairments as they affect how the system works. We divided the self-paced course into easy 4 sections, each of which includes self-paced lectures and unique online "workbooks" that include a summary of the taught formulas and questions for practice exercises or measuring techniques. Each section includes a supplemental on-demand educational webcast that provides a different angle on an associated subject of interest. They include a quick test for each section. Students have their own time to finish the course curriculum, which equates to about 40 hours of training. Keysol Technologies give students who successfully complete the program a signed certificate of completion.
Upon completing the course, you will be able to:
It ideally suited this program for application, manufacturing, and production engineers or technicians who are new to the RF/wireless field. It is also suitable for those who have been working in the field but who have not had a formal introduction to the key concepts that form the basis of understanding and troubleshooting wireless systems. They assume knowledge of basic circuit theory/operation (resistors, inductors, capacitors).
