Claims

[Scope of utility model registration request]

An input terminal for receiving uplink communication signals transmitted from the earth station, a receiver for performing low-noise amplification of the received communication signals and converting them to an intermediate frequency band, and a receiver for converting the communication signals converted to the intermediate frequency band. Narrowband filter for separating into each communication channel; A power divider for distributing communication signals from the narrowband filter as many as the number of service areas; a switch for turning on/off the output of the power divider; and a switch for turning on/off the output of the power divider; a power divider for power-dividing the divided communication signals, a power amplifier for amplifying the power of the power-divided communication signals, and a power for combining the power of the power-amplified communication signals. A repeater comprising a combiner and an output terminal that outputs the output of the power combiner in a number corresponding to the number of service areas.
