Analysis of Low-Noise Amplifier Property Changes by High Power Microwave

초록

Electromagnetic wave output can be paralyzed in an instant the entire system of the country . Study of the specific solution to this has been actively carried out in many countries . In recent years , the electromagnetic wave generator of the high-power be miniaturized , distribution via the Internet , are sold , the risk of terrorism against electromagnetic waves of high power has been increasing even more [1]. A low noise amplifier used in a wireless communication device , and the Sensitivity improved as a high-frequency amplifier stage for amplifying before the change in frequency a high-frequency signal received from the antenna of the receiver[2]. In this paper, we analyze changes in characteristics of the LNA through the high- voltage injection experiments , it is necessary to prepare the protection based on the analysis.
