Abstract :
A method for measuring the noise parameters of MESFETs and HEMTs is presented. It is based on the fact that three independent noise parameters are sufficient to fully describe the device noise performance. It is shown that two noise parameters, Rn and |YOPT|, can be directly obtained from the frequency variation of the noise figure F50 corresponding to a 50 Ω generator impedance. By using a theoretical relation between the intrinsic noise sources as additional data, the F50 measurement only can provide the four noise parameters. A good agreement with more conventional techniques is obtained
