Abstract: This paper represents implementation of a low cost full 2-port vector network analyzer based on six port reflectometer (SPR). It consists two SPRs of different topologies designed at 2 GHz and a power splitter. A full two-port nonlinear calibration method has been followed to determine all the calibration coefficients. After determining the calibration coefficients, the nonlinear equations are solved using Levenberg-Marquardt algorithm to obtain magnitude and phase of S11, S21, S12 & S22 for various arbitrary loads. The results obtained through this system are comparable with that of a commercial VNA. © 2019 IEEE.
