Disruption of a RF front-end subject to an out-of-band signal

This paper deals with the effects of an electromagnetic interference (EMI) from an out-of-band signal impinging on a 2.4 GHz RF receiver operating in the linear regime. The injection signal is radiated in the near-field above the circuit package at a frequency of 60 GHz. Due to the nonlinear behavior of active devices, we observed a gain quenching leading to a complete inhibition of the receiver that occurs together with a current overconsumption. Disruptions are experimentally studied depending on the position above the package, the distance between the EMI source and the circuit, as well as the frequency used to switch on and off the millimeter source.
