Abstract
The present invention relates to an amplifier system for satellites, in particular for radio-frequency amplifier systems incorporating travelling wave tube amplifiers and used in space repeaters. The amplifier system () includes two amplifier modules (A, A) each having an input and an output, a signal divider (D) having an input, a first output, and a second output, a signal combiner (C) having a first input, a second input and an output. The first output of the divider (D) is connected to the input of the first amplifier module (A) via a connection length Le. The second output of the divider (D) is connected to the input of the second amplifier module (A) via a connection length Le. The output of the first amplifier module (A) is connected to the first input of the combiner (C) via a connection length Ls. The output of the second amplifier module (A) is connected to the second input of the combiner (C) via a connection length Ls. The connection length satisfies the equation Le+Ls=Le+Lsand the connection length Lsis different from the connection length Ls.
