The bi-directional power amplifier for the ISM band (915MHz) has been specifically developed for use in devices with a 5V power supply. It provides 20dB gain on reception and 15dB on transmission. Its wide range of applications includes signal amplification for UAV control, SDR radio, amateur radio, IoT, laboratory equipment, and more. We believe that true strength lies in delivering what is promised. Therefore, we guarantee an output power of +35dBm (3.5W) for this tiny amplifier.
