Course Summary

This two-day course provides circuit-level designers with concepts needed to work effectively with high frequency linear amplifiers. Participants gain analytical, graphical, and computer-aided techniques to analyse and optimise RF amplifier circuits in practical situations.  The course addresses linear active circuit design, focusing on stability, bandwidth, and noise considerations.

Learning Objectives

• Perform statistical analysis: design centering, yield optimisation.
• Predict RF circuit stability and stabilise circuits.
• Design various RF amplifiers: small-signal, low-noise, and feedback.

• Match impedances and perform transformations.

Target Audience

Professionals required to work in high frequency domains for the first time, as well as seasoned designers.
