intermodulation distortion

[‚in·tər‚mäj·ə′lā·shən di‚stȯr·shən]
(electronics)
Nonlinear distortion characterized by the appearance of output frequencies equal to the sums and differences of integral multiples of the input frequency components; harmonic components also present in the output are usually not included as part of the intermodulation distortion.

intermodulation distortion

(electronics, communications)
(IMD) Nonlinear distortion in a system or transducer, characterised by the appearance in the output of frequencies equal to the sums and differences of integral multiples of the two or more component frequencies present in the input waveform.

Even without "High-End" power DAC (D class power amplifier) required dynamic range of the measurement devices can be estimated: e.g., Texas Instrument TAS5518-5261K2EVM [2] intermodulation distortion decline for 5th harmonics even -90 dB for output level of 300 / 500 mW (Fig.

One possible way to achieve this design goal is to rely on certain bias points and power operating conditions, the so-called large-signal intermodulation distortion (IMD) sweet spots, which lead to improved carrier-to-IMD ratios (IMR) near the zones where power-added efficiency (PAE) is maximized.
