Microwave Engineering

Institute of Robust Power Semiconductor Systems

This lecture conveys the theory and design of microwave and millimeterwave monolithic integrated circuits (MMIC), covering the areas of microwave network analysis, building blocks and component modelling, circuit analysis, design and physical layout. Students acquire in-depth knowledge and understanding of the design of low-noise amplifies, broadband amplifiers and power amplifiers at microwave and millime-terwave operating frequencies.
