Essential RF Microwave Concepts - A Practical Approach (RF126-4-0)

SynopsisThe rising cost and scarcity of frequency spectrum, the increasing demand for higher data speed and mobility have driven the explosive growth in RF Microwave (RF/MW) industry. Therefore there is increasing many whose work in one way or another is related to this seemingly complex and confusing technical area.

A firm grasp of fundamental concepts in RF Microwave (RF/MW) is important for a fulfilling career in this area, even for those who is not working directly in this industry. For example a basic grasp of the subject area will enable a project manager to appreciate the technical challenge faced in the project or help a mechanical engineer understand why the circuit designer insists on specific technical decision.

With this objective in mind, this course is designed to equip participants with both foundation knowledge and broad appreciation of each underlying application, and therefore increased interest and confidence for their future undertaking. The subject is delivered with minimal complex equations, stressing on practical applications instead.

Course Highlight
This course starts with essential fundamentals of RF/MW. The participants are then taught the measurement theories of commonly-used RF/MW test equipment. Once equipped with the essential concepts and measurement knowledge, the participants are then introduced to the operating principles of typical building blocks of a RF Transceiver (transmitter/receiver).

To conclude the course, an end-to-end walkthrough of each stage of the RF Transceiver is demonstrated with various RF/MW equipments. This serves to show the practical applications of the various subject areas learned in this course.
