Abstract: A device configured to perform second order intercept point (IP2) calibration for a wireless transceiver includes a memory storing instructions, an interface, and at least one processor communicatively coupled to the interface and to the memory. The interface is configured to receive, from the wireless transceiver, a signal including second order intermodulation distortion (IMD2), and transmit, to the wireless transceiver, an in-phase correction code (I-correction code) and a quadrature-phase correction code (Q-correction code). The at least one processor is configured to execute the instructions to analyze a level of the IMD2 based on a plurality of heterogeneous methods, and adjust at least one of the I-correction code or the Q-correction code based on analysis results.
