Article about practical guidelines for LNA design

Not open for further replies.
anybody could tell us if those useful? it is so little.

Is this document useful to design any real LNA? I don't think so.

your can find the full article (3 part) there

Have a look at this article,

PREAMPLIFIER FOR 432MHZ AND 1296MHZ WITH MODERN HEMT-TRANSISTOR (design follows what the datasheet of atf54143 suggests)

**broken link removed**

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...

ATF-54143 is much more expensive. I love ATF-10136.
