PURPOSE:To facilitate communication of small sized earth stations by constituting the titled repeater by a separator separating and extracting a reception signal from each earth station, an amplifier group amplifying the output of the separator independently in response to the scale of the transmission/reception earth station and a coupler coupling again outputs of the amplifiers. CONSTITUTION:A reception signal from an earth station is inputted to an input terminal 100. The reception signal is separated by a separator 1 and extracted at each channel. When the channel is subject to frequency multiplex, the separator 1 consists of a filter groups extracting a signal of each frequency. The output of the separator 1 is inputted to amplifiers (hereinafter AMP) 10, 11, 12, 13 whose gain is variable. On the other hand, a command signal from a control station on ground is inputted from terminals 110, 111, 112, 113 and the gain of the AMPs is commanded. The signal amplified up to a proper level by each AMP is synthesized by a coupler 40, amplified by an AMP 50 and sent to the earth from the antenna 200.
