This course describes the primary components used in typical RF (radio frequency) systems and describes their functions and characteristics as they relate to system performance. Terminology is explained where necessary for the benefit of the non-RF student. The level of discussion is aimed at students who have some familiarity with the concept of RF devices. While this course does not focus on consumer devices, many may be considered as "RF systems" in a broad sense. A cell phone, keychain remote car-door lock control, walkie-talkie, and radio-controlled model car embody many of the same functions found in large systems, such as the weather radar used by TV stations and satellite communications. To that extent, virtually everyone uses an RF system.
Starting from a very basic transmitting and receiving capability, the course introduces the student to system concepts without rigorous technical detail. Those who work in other disciplines will benefit from this course if they need to communicate and coordinate work with RF engineers, define the purpose and requirements for an RF system, or use an RF system in their own work. Future courses in the RF series are planned, depending on student interest, to cover more detail about the function, characteristics, application, and selection of both components and systems.
The student must take a multiple-choice quiz consisting of ten (10) questions at the end of this course to obtain PDH credits.
