Journal of Electronic Systems Elissaveta Gadjeva 12 4 2022 https://doi.org/10.6025/jes/2022/12/4/96-103 https://www.dline.info/jes/fulltext/v12n4/jesv12n4_2.pdf We have introduced a system for receiving the measures for behavioural RF planar. The modalities are based on the S-parameter dependant data. With the help of the macro-definitions in the graphical analyser, we have computer the realization. We have supported the behavioural model with PSpice input language. We have performed the simulation-based experiments that ensure the computer model validity and the procedures for extraction.
