Transmission characteristics of an AC/coaxial adapter that is used for calibration of an AMN had been evaluated up to 30 MHz, which is the upper limit of frequency in the use of conventional AMNs. However, the new type AMNs for using over 30 MHz has been developed, thus the transmission characteristics of the adapter beyond 30 MHz should be evaluated. In this paper, a circuit model of the AC/coaxial adapter is developed in order to obtain easily its transmission characteristics up to 1 GHz. The calculated characteristics using the developed circuit model agreed well with that of simulated by using a numerical electromagnetic analysis.
