Abstract: The subject matter discloses a tower mount amplifier device (TMA device), comprising a reception circulator for receiving a reception signal transmitted from an antenna to a base station and a low noise amplifier unit for amplifying the reception signal. The TMA device also comprises a band pass filter for filtering the reception signal amplified by the low noise amplifier unit and a transmission circulator for transmitting the reception signal filtered by the band pass filter to the base station. In some cases, the tower mount amplifier further comprises a switch for switching the signal from the reception circulator directly to the transmission circulator, wherein the switch operates according to a functionality of the low noise amplifier unit.
