Re: 2.4 lna design narrow bandwidth

Hi, attached is Avago Application Note for 2.3G using ATF36077, G>15dB for one stage, and NF is about 0.5dB.

I don't feel like cascode because it's very easy to osillate at high gain, so I suggest using cascade again.

hello everyone..
we are designing a LNA using Infineon bfp740 and simulated it on AWR Microwave Office. in Infineon website, they gives AWR model of the transistor, but we can not have nonlinear analysis, for example; how can we measure OIP3. it gives the error message "the interception point measurement must specify order two or more"..
could anyone please help us with our problem.
thank you

You need two tones !

i already used two tone signal, which are at 2.44 and 2.46 GHz and -20 dB but it gives the same error again :(

hello
help me for subject the antennas in package for 2.4 GHZ

mi problem is design example for antenna 5*5 multilayer or in package at 2.4

GHz because using this antenna in SiP (System in package).

wat the technologies using for resolution the problem?

tank you

can you help me to select fet at 2.4ghz using ads
