FREQUENCY BIAS CONTROL DEVICE OF SATELLITE COMMUNICATION AND METHOD THEREOF

摘要

PURPOSE: A frequency bias control device of a satellite communication is provided to prevent the biased frequency from badly influencing other satellite channels. CONSTITUTION: The satellite communication system communicating data through a satellite comprises: a high frequency processing unit(300) for converting the IF signal let off from the modulator into the RF signal and outputting by amplifying with the power; and an aromatic coupler(400) for sending the RF signal put out from the high frequency processing unit(300) to the antenna and feeding back the signal sent to the antenna.
