This course is a hands-on introduction to RF and microwave topics, from fundamentals including vector network analyzer (VNA) calibration and operation, power measurements, and antenna characterization, to system-level topics such as RADAR systems and superheterodyne links. Students work in small groups on weekly experiments based on both coaxial and waveguide setups. An understanding of electromagnetic waves (such as covered in ECEN 3400 and ECEN 3410) is assumed. The graduate version of the course (ECEN 5634) includes additional homework and exam problems and extended laboratory exercises compared to ECEN 4634. Same as ECEN 5634.
