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 5690 are to provide you with an introduction to the tools the modern microwave engineer uses in the analysis and design of microwave systems. These tools include a theoretical background in transmission lines and network theory as well as some solid-state devices, a knowledge of modern microwave simulation tools, and the ability to use, perform and understand microwave measurement equipment. Various in-class and out of class assignments will be used to help you in understanding and using these tools.
