2-tone IP2 and IP3 measurement technique

This paper contains the definition and measurement technique of RF-path nonlinearity parameters - 2-tone 2-nd and 3-rd order intercept points, including the case of unequal tone levels. Some recommendations on operation modes of the measuring equipment and its impact on the measurement results are also discussed. The described technique is primarily intended for use with widely available test & measurement equipment such as spectrum analyzer and analog signal generators. The paper can be useful for training RF designers and R&D researchers in the field of RF design.
