High-frequency electronics plays a fundamental role in modern engineering because it enables the technologies that support today’s connected world with applications in the areas of wireless and mobile communications, satellite systems, radars and automotive electronics. For an electronic engineer, understanding microwave electronics is increasingly important since modern systems demand higher data rates, smaller components, and better electromagnetic performance. This course is positioned within four of the Master of Science curricula in Electronic Engineering as an advanced specialization in radio frequency (RF), microwave, and millimeter-wave analog integrated circuit design. It builds upon foundational knowledge acquired in undergraduate courses on electronic circuits, electromagnetic fields, semiconductor devices, analog electronics, and signal processing, extending these concepts toward the design of high-frequency front-end systems for modern wireless and radar applications. By addressing the analysis and design of nonlinear microwave components such as power amplifiers, mixers, and oscillators, the course provides students with the theoretical and practical tools required for the implementation of RF and microwave transceivers in compound semiconductor technologies. A strong emphasis is placed on monolithic microwave integrated circuit (MMIC) design methodologies applied to power amplifiers, and on the use of industry-standard computer-aided design (CAD) environments, enabling students to bridge the gap between theoretical models and practical engineering implementation. CAD activities strengthen professional skills in nonlinear simulation, harmonic balance analysis, impedance matching, stability assessment, and layout-oriented design, which are highly relevant for both industrial R&D environments and academic research.
