Calibration method for a multiport amplifier, multiport amplifier suitable for applying this method and satelite comprising such an amplifier

摘要

method of calibration of a multiport amplifier comprising a plurality of input ports (pe1 - pe4), a plurality of power amplifiers (pa1 to pa4 port (input) connected through a matrix of signal distribution (ibm)a plurality of output ports (ps1 - ps4) connected to the power amplifier through a matrix of the recombination signals (obm), and a plurality of weighting factors (wu1 - wu4) signals associated with said power amplifier; the process is. actu00e9risu00e9 in that it comprises the steps of: determining a normalized cross-correlation in the middle(e) an output signal present at said outlet, taken as reference, and the signals present at the output ports of other known; and adjusting weights of iteratively weighting factors so as to minimize the average normalized cross-correlation or making inf greater than a predetermined threshold.;multiport amplifier comprising a calibration module configured or programmed to implement the method of calibration.;telecommunication satellite payload includes a multiport amplifier.
