Patent ID: 8078094

Claim:
A signal distribution system, comprising: an input subsystem for receiving a plurality of cellular-band antenna diversity signals; an amplifier subsystem with at least two amplifiers for amplifying the received cellular-band antenna diversity signals, each amplifier of the amplifier subsystem amplifying a received cellular-band antenna diversity signal of the plurality of cellular-band antenna diversity signals; an output subsystem for outputting the amplified signals; an output control subsystem for controlling signal levels of at least one output of the output subsystem; and a redundant power supply system for powering the amplifier subsystem, the redundant power supply having a first power supply and a second power supply, each power supply being a primary power supply for an amplifier of the at least two amplifiers in the amplifier subsystem and a backup power supply for another amplifier of the at least two amplifiers in the amplifier subsystem.
