Abstract This study has examined destruction effect on LNA(Low Noise Amplifier) by damped sine wave. DFR(Destruction Failure Rate) was measured to investigate the diagnostic of LNA test. Three kinds of damped sine wave were injected to input port of LNA module: 1 MHz, 10 MHz, and 100 MHz. The destruction level of LNA was assessed by damped sine wave voltage, and its DFR were observed. The destruction of LNA module has showed the degradation of amplification or loss of amplification function. As the frequency of damped sine wave increased, the destruction threshold voltage increased and destruction threshold energy decreased.
Based on these results, the destruction effect of LNA can be used to protect the RF communication equipment from high power electromagnetics.
