A method for the exact determination of noise parameters of active two-ports in the frequency range from 1 to 11 GHz
Abstract
A simplified computer-aided measuring procedure is described that permits determination of the four noise parameters of linear active two-ports in the high frequency range. The conventional ON-OFF noise measuring procedure in the GHz-range (Y-Factor-method) is modified so that the change of the generator impedance between the ON and OFF states does not influence the final result. Furthermore, the proposed method does not need any determination of the noise properties of the receiver stage. As an example, some noise parameters of 1.5 micron-Gate MeSFETs are given in the frequency range between 2 and 10 GH.
