The  IIP3 measurements in the Typical Performance Characteristics section of the datasheet are produced using a specific setup that may not apply for all uses of the transceiver. These measurements capture the IIP3 when large blockers are present in the neighboring bands. This is a common scenario for public cellular radios such as those using LTE. A general purpose radio could have large blockers within the same band as the desired signal, and that setup will produce different IIP3 values. When designing a system, the proper IIP3 data should be used for determining system receiver specs.

 

The document attached to this FAQ shows the measurement methodology and results when considering out-of-band and in-band IIP3 specifications.
