Extraction of noise wave sources in MESFET wave representations

A procedure for extracting the noise wave sources in the wave representations of microwave transistors is presented in this paper. Standard microwave engineer's software tools are used for this purpose. The elements of noise wave correlation matrices are calculated for the device intrinsic circuit which is obtained using a de-embedding procedure. The strength of noise wave sources and the correlation coefficient are shown graphically as a function of frequency and discussed.
