Summary:
Unintentional as well as intentional electromagnetic interference can cause improper functionality of microwave circuits or systems. In this paper, our attention is focused on transient response characterization of microwave MESFET amplifiers, which are used widely in the integration of communication circuits and systems, under the impact of an intentional electromagnetic interference(IEMI) source but with different waveforms, respectively. The mathematical treatment is based on two-port lumped networks FDTD method. Parametric studies are carried out to shows effects of the EMI waveforms, its magnitudes on the transient coupled voltages on the input-output of the microwave MESFET amplifiers, with sufficient information obtained for understanding the interaction between the IEMI source and the microwave MESFET amplifier.
