Abstract
A power amplifier system including: M main power amplifiers and one standby power amplifier, where M is a positive integer; an input switching module, connected to the inputs of the M main power amplifiers and the standby power amplifier; an output switching module, connected to the outputs of the M main power amplifiers and the standby power amplifier. In the system, M groups of signals are inputted to the input switching module, processed by the power amplifiers, and then outputted from the output switching module. The standby power amplifier is independent and is capable of taking place of the faulted main power amplifier immediately without a shut down. In the system there is no correlation between the isolation of various signals and the consistency of the power amplifies, which leads to a substantial decrease of the requirement on consistency of the power amplifiers.
