Abstract
An amplifier system for satellites, in particulars for radio-frequency amplifier systems incorporating travelling wave tube amplifiers and used in space repeaters. The amplifier system includes two amplifier modules, a signal divider, and a signal combiner. A first output of the divider is connected to an input of the first amplifier module via a connection length Le . A second output of the divider is connected to input of the second amplifier module via a connection length Le . An output of the first amplifier module is connected to a first input of the combiner via a connection length Ls . An output of the second amplifier module is connected to a second input of the combiner via a connection length Ls . The connection lengths satisfy the equation Le +Ls =Le +Ls and the connection length Ls is different from the connection length Ls .
