High IP3
Third Order Intercept Point - IP3
The third order intercept point is the most critical specification of a mixer when being used in wireless communications. It is a fictitious number used as a figure of merit to describe the level of performance of a mixer. IP3 is defined as the point of intersection of the extrapolation of the linear primary response of the mixer and the two tone intermodulation response. (FLO ± (2FRF1 ± FRF2), (2FRF2 ± FRF1)).
