I have simulated it, tuned it to my specs and built it (for 450MHZ). The gain obtained was exactly as predicted by the simulation (~23dB). Simulation was suggesting a noise figure of 0.2-0.3dB but I have not verified that yet.
I am an engineer who is developing LNA for IMT Band.
I use ATF-34143 of Agilient..
The spec is NF=0.8dB(typ), Gain=40dB.
The ATF34143's characteristic is very good but is not really..
I used 3stage Amp. ATF34143+EC1019+AH1.
The result is NF0.89, Gain=40dB...
