Popis:	In this paper, the output waveform of EMP coupled to 10 MHz monopole antenna analyzed by simulation, and the susceptibility of LNA(Low Noise Amplifier) was evaluated. The waveform of EMP coupled to the monopole antenna is a 10 MHz damped sinusoidal waveform, and the peak voltage is about 22 kV. The susceptibility of LNAs was evaluated using the 10 MHz damped sine wave generator. DFR(Destruction Failure Rate) was measured to investigate the susceptibility of LNA. The susceptibility level of LNA was assessed by voltage of damped sine wave. The voltage of destruction threshold is 71 V and 107.5 V respectively. The coupling voltage is higher than the destruction threshold of LNAs. Therefore, the communication system can be damaged by EMP. It is necessary to apply the protection device to the communication system. Based on these results, susceptibility of LNA can be applied to a basic data for applying the protection device to the communication system against EMP.
