Hi
What I'm trying to do is create a bias network for avago ATF-34143 transistor model in ADS which matches the plotted S parameters of an S2P file to that of an ADS model of the transistor with a bias circuit. Bias at VDS=3 V, IDS=40 mA.
Both the model and the S2P file of the transistor are obtained from avago's website here:
The S2P file I'm using is the f341433b.s2p - ATF-34143 s and noise parameters at 3 V, 40 mA (1 KB,S2P).
After doing this, the plots for the two simulations do not match. I have don't know why but it's probably the bias circuit I'm thinking.
I've attached some screenshots which should make things clearer.
All suggestions welcome, I am well and truely stuck. Thanks!
