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

I didn't bother to double check the amp against the data sheet and instead went with the voltage recommendations in the Amazon description. This turned out to be an error. I applied 11V and ran the amp for about an hour until I could smell the fried magic smoke coming out of the chip. After that, the RF signal no longer passed through the amplifier. I finally looked at the amplifier and found that the board uses an INA-02186 monolithic microwave integrated circuit for the amplifier, and this particular IC has a typical voltage of 5.5V and a maximum voltage of 7V. I'm not sure if a different chip was used in previous versions, but the one I have is clearly not rated for the voltages advertised.
