Intermodulation calculators.

In case your product, quite often a power amplifier, does not provide you an absolute linear performance, inter-modulation products will be generated, as a result of the non-linear transfer characteristic.

These spurious signals can disturb the operational performance of the system in which the amplifier is used. The limit which inevitably is always there is the internal power supply voltage and the current supply capability of the internal power supply.

In the example below, the third order intercept point (3OIP) is calculated for the power levels of the two test tones F1 and F2 and the power levels of the two inter-modulation products IM1 and IM2.
