Abstract :
For small scale model of STICS satellite beamformer and digital bentpipe system, NICT developed 16-element feeding antenna with Digital BeamFormer and Channelizer for flexible usage of frequency. In the DBF, using NFM measured value and ideal 27mø reflector calculation, we confirmed aimed service area which is +-2.0 degree, can be available. For the channelizer, scalable frequency assignment in case of emergency disaster was confirmed. Such digital transponder technology adapted here will enhance communication satellite flexibility and will establish new era of communication satellite.
