WebTwo-tone third-order intermodulation distortion . Two-tone, third-order intermodulation distortion takes place when two RF signals simultaneously enter the mixer RF port and interact. In practice, this could occur in a multiple-carrier signal environment, or when an undesired signal interferes with a desired one. Of concern is the extent to ... http://www.arcticpeak.com/radiopages/intermodulationproducts.htm In telecommunications, a third-order intercept point (IP3 or TOI) is a specific figure of merit associated with the more general third-order intermodulation distortion (IMD3), which is a measure for weakly nonlinear systems and devices, for example receivers, linear amplifiers and mixers. It is based on the idea that the device nonlinearity can be modeled using a low-order polynomial, derived by means of Taylor series expansion.
