Abstract The effects of highly out-of-band electromagnetic interference (EMI) on a RF front-end are experimentally evaluated. Signal at 60 GHz with a moderate power is produced in the near-field owing to an open-ended WR15 waveguide fed by a Gunn diode. Due to the nonlinear behavior of active devices, we observed a gain quenching leading to complete extinction of either the transmitter or the receiver of the front-end subject to EMI. The paper proposes a detailed analysis of both CW and chopped EMI by varying almost all experimental conditions, namely the polarization, the target distance, and the chopping mode.
