Abstract
Reconfigurable RF front-end circuit for a multi-beam array fed reflector antenna system having a first plurality of Ninput beam signals and a second plurality of Nradiating 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 Ninput ports and distributing each input port signal to a plurality of Noutput ports with phase and amplitude control, a plurality of Nhigh power amplifiers (HPA) connected to the plurality of Noutput 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 Nradiating elements (RE). The high power amplifiers (HPA) are variable bias high power amplifiers (VB-HPA).
