摘要
Abstract
Transparent transponder mainly receives signal ,and amplifies it at the price of low noise ,and then launch back to the ground .Because of its simple structure ,it is one of the currently used .But owing to the nonlinear amplifier fea‐tures of the traveling wave tube(TWTA) of transparent transponder ,when multiple carriers go at the same time ,it will re‐sult in serious intermodulation interference .In this paper ,aiming at the phenomenon ,within 0 ~ 36M Hz bandwidth ,we ana‐log multiplexer carrier repeater amplification process with the Matlab simulation .Through the experiment ,we reaserch on the multicarrier intermodulation interference ,and find it will be more rational to distribute channel and we can make the best use of the repeater communication capacity too .关键词
