Good LNA choice - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

I am looking for a good LNA ( low NF, high IP3...) for VHF and UHF receiver design.Anybody has experience or knows a good one?
Is possible to improve the input return loss of LNA with external component structure?
If you have to choose for a new design double conversion receiver or direct conversion receiver which one you perform?

I have had good luck with Avago MGA-62563. It has .9dB NF, 33dBm OIP3, 22dB gain at 500 MHz. It also has current adjustment (via resistor value) to optimize for desired performance.

Try the Amplifier search on http://www.everythingrf.com
Just enter the specs and click on search. It searches components from over 100 manufacturers.
You can specify the NF and Gain.
