Abstract
A noticeable source mismatch occurs in measurements of noise parameters of a linear two-port, since an admittance-transformer network between the source and the two-port must be inserted. A generalized analysis of the source mismatch effects on noise measurements, which considers the dependence of the noise performance of the two-port on the input admittance, is presented here. On this basis, two types of noise generators are considered and compared with each other.Keywords
