The intermodulation distortion (IMD) performance of
wideband, DC-coupled amplifiers is a relatively new area
for integrated operational amplifier suppliers. New progresses
in IC technology extend the application of op amps where
some years ago discrete circuits played the major role.
Methods to measure and communicate the extent of this
distortion to users have been borrowed from traditional
“RF” companies which have historically supplied the radar
and radio communications industries, where the importance
of it was first highlighted.
Examples of applications demanding good intermodulation
distortion include:
• Radar
• Satellite Communications
• Digital Radio Receivers
• Nuclear Particle Research
• CAD Monitor Amplifier
