Review on 📻 HiLetgo 0.1-2000MHz RF WideBand Amplifier: High Gain Low Noise LNA for Enhanced Signal Performance by Andrea Hemphill

Seems to work best at 9 volts. The gain below 7 volts is lower and the noise introduced by this increases noticeably on the oscilloscope at 10-12 volts. Feeding it a well-regulated 9 volts seems ideal. I tested mine with a signal generator up to 100MHz and found the gain to be around 20-25dB. If you go to 12 volts you can get it up to the advertised 30dB but with the increased noise I'm pretty happy to keep it at 9 volts with less noise. One of these goes to an ADSB receiver and I'm sure it will work fine, but I don't have a test unit that runs at >1GHz.
