Abstract

The cascade noise model

and the noise parameters extraction of microwave BJT device were studied.Using the complex correlation theory

the expressions of the noise parameters

min

opt

were obtained.According to the intrinsic H-parameters and noise source configuration of the two-port device

the

-I

model equations are determined.By substituting the

-I

equations into the noise parameters expressions

the noise parameters are extracted.The experiments on the two devices AT41410 and AT41411 show that the results extracted are almost in accord with the values measured.
