Summary:
This course aims to bring participants up to speed on the basics of RF power amplifier design and operation in the shortest possible amount of time. Considerable attention is devoted to defining, classifying, and improving the efficiency and linearity of power amplifiers. Numerous design examples are provided for participant exploration. The class offers approximately one day's worth of material, but is typically offered in five 90-minute sessions via web-classroom.Learning Objectives:
Upon completing the course, the participant will be able to:- Design low distortion and efficient power amplifiers.
- Bias power amplifiers for class A, A/B, B, and C operation
- Understand the tradeoffs among the classes of operation.
- Design amplifiers for gain or power or a compromize of the two.
- Describe several techniques used to linearize power amplifier output.
- Utilize modern circuit simulators and a simple system simulator.
- Understand the effect of harmonics on PA performance.
Target Audience:
Component and system level designers, as well as engineering managers will benefit from this course. RF/wireless engineers who wish to expand their circuit design skills from basic linear design techniques to nonlinear methods, or just wish to understand power amplifier performance at the design level. Basic knowledge of microwave measurements and transmission line (Smith Chart) theory is assumed.Outline:
