Hallo,

is this usable as an linear amplifier really? Which graph gives linearity information? I tested some amps in the past. SG-Lab, Dx-Patrol, AMSAT, DB4UM, PA3AXA, PE1RKI and so on. Single tone saturation power is the wrong information. The linear range was less always. But, the good news is, all amps were usuable for QO-100-Operation, the linear power was enough in all cases but did not correspond with the manufactures data. As written often already, power information should be given together with a specific intermodulation distortion.
For microwave cooking, the linearity isn't important at all but for a good SSB-Signal it is. It would be nice and very helpful if all the developers and manufacturers show a spectrum of their amps. It is very easy even at 2,4 GHz. LimeSDR Mini and Adalm Pluto in combination with the SDR Console are excellent two tone generators with very low intermodulation distortion.
By the way, wideband signals require a good linearity also.

Hi all...

so the best way should be...

use commercial modified amplifiers from 4G base station oringinal for 2.2G ....doherty style and very cheap to get in the net
can be modified for 2.4G sometimes but not all models work...

WORKING GREAT in linearity efficiency and output also for WB on QO-100

I wonder for what?
