Dear Community,
I am considering to use the QPA9119 as wider band power amplifier but in the datasheet there is not specification about its linearity after 2170MHz, even if it mentions 400 - 4200 MHz as frequency range.
Did you test it at frequencies higher than 3GHz (for instance at 3.5 or 4 GHz)? Do you have some performance plots or typical values in this frequency range?
Thank you
