Course Synopsis
This course
covers laboratory measurements typical of those used to characterize
microwave devices and systems, such as wireless transmitters and receivers,
radars, radiometers, etc. This includes: network analyzer calibration;
measurements of noise in amplifier, mixers, and oscillators; measurements of
distortion in amplifiers and mixers; and characterizing the dynamic range of
a receiver.
