DISPOSITIF D'AMPLIFICATION DE PUISSANCE DE CHARGE UTILE D'UN SATELLITE MULTIFAISCEAUX DE DIFFUSION DE DONNEES

摘要

The device has a set of power amplification circuits comprising inputs to receive data signals to be broadcasted. A set of switches comprises input terminals connected to output terminals of the power amplification circuits. A set of addition networks connects the output terminals of the switches to broadcasting antennas (40, 41). A set of switch controlling units operates the switches such that two input branches of nodes of the addition networks are simultaneously supplied with an identical signal having same power. An independent claim is also included for a multibeam satellite for broadcasting data.
