Resum
This paper describes a measurement setup to obtain the reflection coefficient response over the frequency of a given device when this is subjected to a single-tone high-power (HP) signal. The proposed system is based on a feed-forward technique to cancel the reflected HP signal before reaching the vector network analyzer. This allows measuring the effects of the HP interfering signal into the device's low-power frequency response. This technique does not require either power-calibrated standards...
