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...
In the framework of a near-field remote sensing imaging experiment we developed an interferometric detection scheme at the open end of the rectangular waveguide that serves as probe. To proceed with lock-in detection, the Gunn source is further switched at kHz frequencies. This results not only in an intensity sensitive image of the sample but also in a phase-contrast image that bring complementary...
