ADALM-Pluto SDR as a Tool for S-parameter Estimation: A Comparative Study of Various System Identification Procedures

In this work we propose an affordable measurement setup for scalar network analysis using ADALMPluto software defined radio and a number of system identification procedures used for the purpose of estimating magnitude of S-parameters. The proposed algorithms are employed for the purpose of estimation of the S-parameters of passive microwave circuits. A comparison of these procedures is given considering measurement of magnitudes of transmission and reflection coefficients with respect to frequency.
