This model shows how to perform intermodulation analysis of the amplifier block from the RF Blockset™ Idealized Baseband library.
Fig. 1 Idealized Baseband amplifier intermodulation example model:
Fig. 2 Spectrum of the input two-tone signal:
The following figure shows the spectrum of the output signal of the Idealized Baseband amplifier. You can see the intermodulation generated by the amplifier's nonlinearity.
Fig. 3 Two-tone output:
To view the intermodulation performance at the output, double click the Slider Gain blocks and change the gain while the model is running.
