Probing RF front-ends vulnerabilities to high power electromagnetic interference, case study of a GaAs HEMT low-noise amplifier.

In this PhD thesis dissertation, a study of a GaAs low-noise amplifier (LNA) susceptibility to high power electromagnetic interference is presented.
The term high power electromagnetic interference refers to a particular electromagnetic environment in which E-filed and H-field levels are high enough to cause physical damage to the victim system's electromagnetic components.
Such high-level field can be generated by dedicated systems, called electromagnetic directed energy weapons (DEW).
The study presented in this document focuses not only on explaining failure mechanisms triggered by such interference, but also shows discussion on electromagnetic sources parameters trimming influence on component's susceptibility.
