I am looking any nonlinear model of
discrete transistor about 8 GHz to 12 GHz, 4W.
I want to design power amplifier and
I need model to simulate loadpull
The SPICE or Model parameters are available by signed agreement between a real customer and manufacturer at those frequencies and in that power range.
Because these components critical military class,professional comm. grad. space qualified elements.That's why manufacturers such as Triquint, Nitronex, Macom, Cree etc. don't give the model data unless you proof that you are "real customer" or scientific researcher.
