This three-day course combines theory with real-life examples to provide participants with a complete foundation in digital communication techniques and their effects on RF circuit parameters, to help them close the gap between traditional RF engineering design and the needs of modern communication systems.

Learning objectives

Upon completing the course you will be able to:

  • State digital wireless communication system concepts and performance limitations.
  • Analyze system degradation due to RF components.
  • Develop wireless communication system budget profiles.
  • Calculate propagation lossess and link budgets.
  • Assess cost vs. performance issues.
  • Evaluate the performance of differing RF wireless system architectures.

Target Audience

Professionals required to work in high frequency domains for the first time, as well as seasoned veterans, will benefit from this comprehensive overview of practical design techniques. An electrical engineering background (BSEE or equivalent practical experience) is recommended, as well as a familiarity with complex numbers.
