Hi all,
I am looking to gain information on EVM specs and how one measures EVM (I know the power definition) but what equiptment is use and what does it does it do that a PNA can not do?
What amplifiers are better for which EVM specs (ie GaAn or GaAs for example). Does anyone know any good papers or books on such subjects?
With GaAs the EVM usually gets better (device gets more linear) as one gets further and further away from the compression point, is this also true with GaAn devices?
Is EVM all about the linearity of the device?
Thanks all,
Babbage
