This course presents a selection of advanced topics related to modern microwave and wireless communications technologies: - Microwave oscillator design: frequency stability, phase noise origins, analysis, phase-noise measurement, and approaches to building low-phase-noise oscillators. - Microwave amplifiers for use with high bandwidth-efficiency modulations: analysis of non-linearity, digital pre-distortion (DPD), feed-forward (FF) amplifiers, achieving linearity. - High-power microwave amplifiers: power combining, synchronization, high-power RF system passive and active components (switches, limiters, junctions, directional couplers), and linear amplification with non-linear elements. - Microwave modulation and demodulation technology, homodyne and heterodyne detection, polyphase receivers, software-defined radio technology. - Antenna impedance and polarization matching, antenna aperture efficiency, phased array antennas and MIMO systems with emphasis on the RF front end. - Advanced topics in thermal design and management of microwave and RF amplifiers. *** The course includes lectures and individual consultation, and one practical project that may include one or more of design (simulations), building a circuit, and characterizing it - topic to be decided between the teacher and student on an individual basis.
