Hi Airy -

I'm not sure what "answer" you're referring to here. But if you're
referring to the question about IP3 applying to amplifiers, the
answer is a resounding "yes"--as noted in posts above.

As a matter of fact, IP3 is often most useful when applied to an
entire chain of cascaded devices such as mixers and amplifiers.

Regarding your comment about an amplifier possibly "clipping...
before non-linearity," that is impossible by definition--because
clipping IS a non-linearity.

But it is possible to find amplifiers that are extremely linear
below clipping, and which clip very abruptly. Such amplifiers
may show relatively poor conformity to the intercept point model,
which was based on more gradual nonlinearities.

I don't know the answer to that, and you are as capable of
looking it up as I am.

If an amplifier, then perhaps you'd run into clipping problems
or rail problems before non-linearity?

The better a mixer is, the higher is IP3 for the outputs of the mixer.
Am I correct in assuming the device need not be a mixer? Could it be an
amplifier? In which case some of the better or worse parameters would
just
become meaningless.
