RF Technology Certification
This online program has been designed for applications, production, manufacturing engineers and technicians as well as other professionals who need to have a solid background in the fundamentals of working with RF and wireless products. This four part program provides a thorough understanding of RF analytical tools, communications signals, RF devices and test instruments. Starting with basic analytical tools such as the decibel scale, S-parameters and the Smith Chart, this program covers test instrumentation, RF components, and modulation. A basic block diagram of a transmitter/receiver chain forms the backbone of the course outline. Each component is described, and the relative performance parameters defined. Key impairments are introduced as they become relevant to the operation of the system. Basic system calculations are covered, as well as modulation formats and multiple access techniques.
The self-paced program is divided into four parts, each consisting of pre-recorded self-paced lectures followed by custom online “workbooks” that contain a summary of formulas learned and practice exercise questions or measurement procedures. A bonus on-demand tutorial webcast in each part offers an additional perspective on a related topic of interest. Each part has a brief test as well. The program is equivalent to approximately 40 hours of training and students are given six months to complete the material. After finishing the program students will receive a signed certificate of completion.
This course is intended for registered individual students only. Please contact us for group rates at [email protected] or 650-949-3300. Recording, copying, or re-transmission of classroom material is prohibited.
