I tried to design an LNA before using ATF55143, but I see they became obsolete. What can I use now for a 2-3 GHz low noise HEMT?
 

Nowadays, it's really hard to find discrete HEMT or its variants transistors.Almost all IV-V Compound Semiconductor Companies are going with with Dedicated Integrated Products and discrete components are rarely found at some few manufacturers.
If I were you I'd consider SiGe from Infineon..
