Differential and Common Mode Noise Waves and Correlation Matrices

This paper presents an innovative extention of the noise wave definition to mixed mode, differential - and commonmode noise waves which can be used for noise analysis of differential microwave networks. Mixed mode noise waves are used next to define generalized mixed mode noise wave correlation matrices of microwave multiport networks. Presented approach may be used for noise analysis of microwave differential networks with differential ports as well as with conventional single ended ports.
