Summary

This five day course provides engineers with the fundamental concepts needed to work effectively with high frequency wireless circuits and systems. Participants gain analytical, graphical, and computer-aided techniques to analyze, test and optimize RF circuits and systems in practical situations. The course also addresses RF measurement techniques as they apply to today's wireless products.

Learning objectives

Upon completing the course you will be able to:

  • Describe RF circuit parameters and terminology.
  • Understand the effects of parasitics on RF circuit performance.
  • Understand wireless architectures and system specifications.
  • Analyze system degradation due to RF component variances.
  • Understand the tradeoffs between power efficient and spectral efficient modulation techniques.
  • Understand RF system test standards and measurement techniques.
  • Describe test requirements needed for new wireless networks (Bluetooth, Home RF, 802.11, etc.).

Target Audience

Engineers, programmers, chip designers, and engineering managers involved in the design, planning, implementation, or testing of communication systems would benefit from this intermediate-level course. Participants should have a BSEE or equivalient.
