Amplifier for 0.5Ghz non linear behavior

[yefj]

Hello, i want to create a square wave with my controller and using RC circuit to create a sine wave, and use it as an input for an amplifier to see the iip1 iip3 points on the spectrum analyzer (3Ghz spectrum analizer)

Is the such a component you would recomment so i will do a cascade of them to see on the last stage the CLIPPING of the sine wave and analyze IIp3 from it.
also i want to do impedance matching for it.
If there is such a component i could put on a bread board i would appriciate suggestion.
Thanks.

I'm not getting the point of this - IIP3 is supposed
to be a measure of channel linearity, for "pretty
good" signals. If you're going to clip it, that seems
like you'd be measuring garbage.

IIP3 is a frequency-point and so to get it you
need measurements at multiple frequencies
so you can extrapolate. Using a RC filter on a
varying frequency square wave will make you
a varying-amplitude varying-frequency sorta-
sine (with embedded harmonics, varying also)
and how are you going to take that effect out
of the data?
