Corporate amplifier apparatus with improved degradation

摘要

A corporate amplifier is defined as and includes a plurality of N amplifier modules where N is a positive integer that is greater than one. The plurality of amplifier modules are driven by a power splitter which takes a signal that is to be amplified and divides it into N equal amplitude components. Each component is applied to a member of the plurality of N amplifier modules for amplification. The outputs of the power amplifier modules are combined by a power combiner that has N input terminals with each input terminal being connected to an output terminal of a member of the plurality of N amplifier modules. A fault detector detects failure of one or more of the plurality of N amplifier modules and provides a fault signal indicating thereby a failed amplifier module. A compensation circuit compensates both the power splitter and the power combiner means so that if a fault is detected in one or more of the plurality of N amplifier modules the performance of the corporate amplifier will be optimized.
