ABSTRACT:
A split-band, redundant amplifier system is disclosed. The system has at least two identical amplifiers (1, 2) each capable of amplifying signals having frequencies within a predetermined pass band. A first filter (3) divides signals into at least two contiguous split-bands within the pass band. A second filter (5) combines the signals in the split-bands. In normal operation, the amplifiers are connected in parallel between the two filters, and each amplifier amplifies signals in only one of the split-bands. Switches (SW1, SW2, SW3, SW4, SW5, SW6, SW7, and SW8) are connected to the amplifiers and the filters and are operative to selectively connect an input signal to the first filter or to one of the amplifiers and to selectively connect the output of the second filter or the output of one of the amplifiers to the output of the system. A sensing circuit (7) is connected to the outputs of each of the amplifiers and detects when an amplifier becomes inoperative. When an amplifier becomes inoperative, the sensing circuit disconnects the inoperative amplifier from the first and second filters and connects an operative amplifier to the input and output of the amplifier system.
