Works as described, great price!

I had no problems with the device I received. I used a simple USB power supply soldered to the terminals on the board. it consumes about 75 mA. As with LNA, this should work as long as you have filtered out strong local signals before accessing this device. In some quick lab tests it showed a gain of 16-19 dB over a wide frequency range. When inverted and used as a power amplifier, it can deliver around 100 mW (+20 dBm) into a 50 ohm load.
