RF Systems: Fundamental
Concepts
Edwin A. Carrell, P.E.
Overview
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
cellphone, 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.
