IIP3 (Input-referred Third-order Intercept Point)
The extrapolated input power at which a circuit's third-order intermodulation products would equal the wanted output, used as a linearity figure of merit. Higher IIP3 means the receiver tolerates larger nearby blockers.

Notes
A rough rule of thumb puts IIP3 about 10 dB above the input 1 dB compression point for many amplifiers.
