Abstract
An amplifier system an amplified path and a bypass path for carrying an RF signal. A switch in the amplified system routes the RF signal through the amplified path in response to a normal condition in the amplifier system, and routes the RF signal through the bypass path in response to an abnormal condition in the amplifier system. The amplified path includes an amplified forward circuit and a return circuit. The amplified forward circuit has an amplifier, and the return circuit has a return amplifier and detection circuitry for providing power to the return amplifier. The detection circuitry provides power to the return amplifier in response to a normal condition in the return circuit, and removes power from the return amplifier in response to an abnormal condition in the return circuit.
