As part of a NSF-funded Project, Portland Community College has developed a series of low-cost experiments to teach transmission line fundamentals and impedance matching techniques. Using a MFJ-259B SWR Analyzer, experimental exercises to measure reflections coefficients, standing wave ratios, and input impedance have been developed and used in the teaching laboratory. With the addition of a matching unit and simulated load, impedance matching exercises can also be implemented. These laboratory exercises were classroom-tested during Winter Term of 2003 at Portland Community College in a three-credit course entitled MT 240 RF Plasma Systems. This paper describes these experiments.
