Modern communication systems, regardless of whether the system is primarily digital or analog, all require high frequency systems to extract or inject the appropriate signal into the transmission medium. The course objectives of ECE 8671 are to follow up on the theoretical material in the previous course (ECE 8670 Microwave Theory and Techniques I) and to provide you with the additional tools the modern microwave engineer uses in the analysis and design of microwave circuits and systems. These tools include a theoretical background in transmission lines and network theory, transmission line filter theory, solid-state devices and circuits, and knowledge of microwave simulation tools. Various in-class and out of class assignments will be used to help you in understanding and using these tools and their application in various problems.
