Unconditional Stability Analysis of N-Port Networks Based on Structured Singular Value Computation
<|reference_start|>Unconditional Stability Analysis of N-Port Networks Based on Structured Singular Value Computation: In this paper, a novel approach based on robust stability concepts and tools is introduced to evaluate the unconditional stability of microwave active $\textit{n}$-port devices. An efficient calculation of the Structured Singular Value of the $\textit{n}$x$\textit{n}$ scattering matrix is proposed to obtain the stability characteristics of the device. The presented method is validated in two ways. First, it is applied to a referential 4x4 scattering parameter set for independent verification. Second, the method is applied to a 4-port GaAs FET amplifier fabricated in hybrid technology. The results confirm the validity and computational efficiency of the proposed approach.<|reference_end|>
