Distortion and Distortion Parameters


The goal of this article is to present the subject of distortion in RF devices without making blanket statements or assumptions that have no academic support, while at the same time keeping the mathematics to an acceptable level without sacrificing academic integrity.

It is possible that by using the concept of polynomial representation of device nonlinearity, together with the technique of sinusoidal signal multiplication, the subject of distortion can be presented in a simple, yet thorough, way. This approach can also be used to explain the true meaning of the many distortion parameters found in RF engineering by linking them to the basic concepts of distortion.
