Abstract
Intermodulation distortion (IMD) is a common problem in a variety of areas of electronics. In RF communications in particular it represents a difficult challenge to designers who face tougher requirements on component and sub system linearity. This trend is driven in part, by an increase in radio spectrum congestion. This paper aims to identify the mechanisms responsible for generating intermodulation distortion and to examine some of the methods which may be used to measure and combat the problem. The emphasis is largely directed towards radio communications, yet many of the principles are directly applicable to other fields of application. Where appropriate, examples of real test applications are introduced.
