Abstract
Cables play an important role in transmitting energy and information. In this article, in order to obtain the S-parameters of the special twisted pair cable with rectangular connectors, a de-embedding method of the transmission matrix is proposed to deal with the two adapters ends of the cable. According to the frequency-dependent RLGC(f) model, the cable characteristics are extracted in the frequency range of 10 MHz to 200 MHz through conventional and modified methods respectively. The frequency-domain analysis shows that the inherent capacity of modified method can decrease the errors especially due to the discontinuities of hyperbolic functions. This research supplies an advantageous modelling approach for the cable to improve its robustness against disturbances in the S-parameters measurement that cannot be decreased with the calibration procedure.
