This method would simplify the test sequence and keep the acceptable tolerance to measure the attenuation of a two-port device under test (DUT). An auxiliary circuit is implemented to respond to different impedances at different frequencies as a terminator at the second port of the two-port DUT. Formulation to reconstruct the two-port DUT is presented. This one-port measurement method provides acceptable accuracy in measuring attenuation coefficients compared to the conventional two-port method. The formula of the reconstructed two-port S-matrix is verified by experiment in the frequency range from 8 GHz to 12 GHz.and measurement method | calibration | one-port measurement | S-matrixconference paper10.1109/APMC57107.2023.104396642-s2.0-85186715734https://api.elsevier.com/content/abstract/scopus_id/85186715734
