Learning Outcomes
1. Scattering matrix and other matrix representations. 2. Waveguide excitation via probes and aperture coupling. 3. Detailed analysis of 3- and 4-port typical passive networks, such as the Wilkinson divider, 90o or 180o hybrids (rat race) or coupled-line directional couplers. 4. Some elements on microwave filters. 5. Understanding of ferrite material properties and the operation of ferrite devices. 6. Microwave PIN diodes and associated circuits (switches, phase-shifters, etc). 7. Thorough understanding of microwave transistors (stability, gain) and design of single-stage microwave amplifiers.
