Concept
The third-order intercept point (IP3) is a figure of merit used to quantify the linearity of a radio frequency device, indicating the power level at which third-order intermodulation distortion products become significant. It is a hypothetical point where the power of the third-order products would equal the power of the fundamental signal, assuming linear extrapolation of both curves, and is crucial for assessing the performance of amplifiers and mixers in communication systems.
