  • Reconfigurable RF front end circuit for a multi-beam array fed reflector antenna system
    Patent number: 10347986
    Abstract: Reconfigurable RF front-end circuit for a multi-beam array fed reflector antenna system having a first plurality of NB input beam signals and a second plurality of NE radiating elements (RE), and method of operating such a front-end circuit. The front-end circuit comprises a reconfigurable beam forming network (LLRBFN), having a set of NB input ports and distributing each input port signal to a plurality of NA output ports with phase and amplitude control, a plurality of NA high power amplifiers (HPA) connected to the plurality of NA output ports of the reconfigurable beam forming network (LLRBFN) and an output network (ONET, OSN), arranged for recombining signals output by the high power amplifiers (HPA) and feeding the recombined signals to the second plurality of NE radiating elements (RE). The high power amplifiers (HPA) are variable bias high power amplifiers (VB-HPA).
