system with leistungsverstu00e4rkern in parallel and with a reserveleistungsverstu00e4rker as replacement or zusatzleistungsverstu00e4rker

摘要

This invention discloses a power amplifier system including: M primary power amplifiers and a backup power amplifier, in which, M is a positive integral, an input switch module connected with the inputs of the primary and the backup power amplifiers, an output switch unit connected with the outputs of the two amplifiers , in the system, after the M signals are input into the power amplifier and processed by the input switch module, they are output by the output switch module, the backup power amplifier in this invention exists independently, which can replace faulty primary power amplifiers immediately without stopping.
