Three kinds of microwave and RF measurement techniques are commonly used and have been introduced in this chapter. One is the S-parameters measurement technique for small signal device and circuit characterization. The vector network analyzer is the key instrument, and its calibration can be carried out by using error model with SOLT, TRL and LRM methods. Noise figure is a figure of merit in RF systems and components, and can be determined from noise measurement technique by using the Y-factor method. Then the power measurement technique, which includes the power gain compression, harmonic distortion and inter-modulation distortion measurements is introduced.
