Summary

This course is the first in a series for RF Design engineers and other professionals in that field. It presents core concepts essential in understanding RF technology and presents circuit-level designers with the foundation needed to work effectively with high frequency electronics. Participants gain analytical, graphical ( Smith Chart ), and computer-aided techniques to analyze and optimize RF circuits in practical situations. This course reviews traditional circuit definitions based on voltages and current and transitions to power-flow concepts and scattering parameters (S-parameters) used in the wireless domain.

The material covered forms the foundation for follow-on courses dealing with specific RF and Microwave circuit and component design.

This seminar contains material typically covered in one full day of instruction but is divided into five 90 minute web-classroom presentations.(9:00am to 10:30am Pacific time) Each daily session is a live online event but the recording can be made available on demand and online to support students requiring a more convenient viewing time. For on demand students, simply register online or by contacting the office and you will receive the login details for 30 day access to the recording.

This course is intended for registered individual students only. Please contact us for group rates at info@besserassociates.com or 650-949-3300. Recording, copying, or re-transmission of classroom material is prohibited.

Students will receive a signed Certificate of Completion on request.

Learning objectives

Upon completing the course you will be able to:

  • Describe RF circuit parameters and terminology
  • Work comfortably with dB notation
  • Understand Modern CAE/CAD Techniques
  • Work with transmission lines
  • Use graphical design techniques and the Smith Chart

Target Audience

The course is designed for professionals working in the RF domain for the first time as well as seasoned veterans requiring a good review of the core concepts. An electrical engineering background (or equivalent practical experience) is recommended, as well as a familiarity with complex numbers. This program prepares students to take the follow-on RF Design: Applied Techniques course.
