Abstract :
An automatic measuring system has been developed that performs the simultaneous determination of noise (N), gain, and scattering (S) parameters of microwave transistors through noise figure measurements only. This complete characterization of active devices allows the extraction of accurate circuit models suitable for CAD of monolithic microwave integrated circuit (MMIC), low-noise amplifiers. For eight samples of the high electron mobility transistor (HEMT) 2SK677 by Sony, the comparison between the measured and the modeled N and S parameter sets is reported
