Hi guys!
I've been trying to design an LNA using BJT transistor, on the first try the results of my simulations and measurements were different and i concluded that it must have been related to the permittivity of the substrate (i had a resonator on the board) . so i redesigned the LNA using the correct permittivity this time but still no luck.
So i was wondering how accurate the transistor model is actually? and if they are not 100% accurate how does a person design correctly their amplifier?
I'm working at 10GHz.
Thank you in advance.
