Abstract
In order to investigate the effectiveness of an SMA receptacle as wideband measurement electrode for human ESD, we derived the transfer impedance of a 50-Ω SMA receptacle, and measured its frequency characteristics from 300 kHz to 20 GHz. With a 12-GHz digital oscilloscope, measurement of discharge currents through a hand-held metal bar from a charged human was made, and thereby the injected currents on the SMA receptacle were reconstructed from the measured transfer impedance. The results show that at a charge voltage of 1500 V the reconstructed current waveform agrees well with the observed voltage waveform divided by 50 Ω.
