### Differential Noise Figure and Gain De-Embedding: the Wave Approach

#### Abstract

**The paper presents complete analysis of differential amplifier noise figure single-ended measurement setup. The analysis is based on scattering matrix representation for the network and wave representation for noise. As a result, there are presented equations allowing the differential amplifier gain and noise figure to be de-embedded with single-ended measurements. De-embedding equations are given for the balanced amplifier and for the fully differential amplifier. **
