Abstract: A unified, integrated bi-directional Radio Frequency (RF) amplifier comprising a unitary housing having walls adapted to allow communication therethrough, a power amplifier, a RF signal filter and an internal electrical backup power source, wherein the power amplifier, the radio frequency filter and the internal electrical backup power source are integrated within a BDA all enclosed by the unitary housing. In one embodiment, the internal electrical backup power source is a lithium-ion battery or battery array. In another embodiment, the amplifier may be electrically coupled to an external power source and to an internal backup power supply.
