TQP3M9037-LNA Gain Test

I picked up a TQP3M9037-LNA off of the 'zons. Putting my RIGOL DSA815 Spectrum Analyzer & Tracking Generator through it's paces to measure the gain from this LNA.

Wow, this is so underrated, your voice is so relaxing and chill and you have really great content, I love how to explain everything in detail. You definitely gained a subscriber :)

I bought a very similar LNA from Amazon. Works well enough.

Good presentation, now you just need a noise figure meter to really charactorize it! My measurements at 2304Mhz were about 18db gain with NF of .78? (noise head a little out of cal). Not bad at all for $15 device. Like ablaauw, would have like to have seen inside...

What is the maximum input on this little amp? I need just a little more power on my Lora iGate to reach my friends house.

very good video, however, could you please give us some tricks to identify false product before buy it?

I see -25dB turned off. Does it means that it is not going through when is off and it has such attenuation please?

13:40 What thing, please? :) Overtightening the SMA connector?

I would have liked to see what's is in the box. it looks nice, seems perfect for the Hackrf One. Just look further to see if anyone has already opened it so you can see what's going on inside.

Does this amplifier work for transmission? Make your broadcast stronger?

how does it hold up to lower frequencies, especially from 100-200khz?
