Hi everybody!!

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.

Good luck!!

Try the Amplifier search on
Just enter the specs and click on search. It searches components from over 100 manufacturers.
You can specify the NF and Gain.

Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
