Works as described, great price!
I did not have any problems with the device that I received. I used a simple USB power supply soldered to the board's terminals; it draws about 75mA. As a LNA, this should work as long as you have any strong local signals filtered before the input to this device. In some quick bench testing, it has 16-19dB of gain over a broad range of frequencies. When turned around and used as a power amplifier, it appears to be able to deliver up to about 100mW (+20dBm) into a 50 ohm load.

Worked perfect as described, until it quit today!
Worked perfect up to yesterday, drawing around 88 milliamps, and today quit, drawing up to 1 amp! All at 5 volts. Reqlly disappointed. Of course, it's past its return date.

Not so good
They work well with HackRF one for a temporary solution to blown pre-amps. However after a few weeks to a month they just die out. I do not leave amps on only on when in use.

No Joy, can't recommend
No joy, very noisy. Also, not very efficient. Consumes about 100 ma. at 5 Volts I measure about 20 dBm gain.

Arrivato non funzionante
Purtroppo non ho fatto in tempo a fare il reso. L'articolo è arrivato non funzionate nonostante le diverse prove.. Ricordo inoltre che è unidirezionale, applicabile in sola RX oppure solo TX.

Risposta non lineare dopo i 300MHz
Consegnato velocemente da Amazon. Si è rivelato di discreta fattura, nella media dei prodotti made in China. Un po' rumoroso e con guadagno decrescente già dopo i 300MHz

Ok
