Calibration Procedure multiport amplifier, multiport amplifier enabling implementation of a method of this kind and satellite comprising such an amplifier

摘要

Calibration procedure a multiport amplifier comprising a plurality of input ports (PE1 - PE4), a plurality of power amplifiers (PA1 - PA4) connected to said input ports via a distribution matrix signals (IBM) and a plurality of output ports (PS1 - PS4) connected to said power amplifiers via a matrix recombination signals (OBM) being adapted such matrices distribution and recombination of signals to deliver a signal on a so-called input port among a plurality of said power amplifiers and recombining said signal, amplified, the level of a so-called outlet port being associated element weighting signals (EP1 - EP4) each called power amplifier; the method being characterized in including the steps of: a) determining an average normalized intercorrelation between an output signal present in a so-called output port, taken as reference, and the signals on the other called output ports; b) iteratively adjusting weights of said weight elements, such that said average normalized intercorrelation is minimized or becomes lower than the a predetermined threshold.
