Abstract

PURPOSE:To improve the flexibility and utilizing efficiency by using 1st switch matrix to select the frequency slot, and selecting the down link beam by 2nd switch matrix, thereby allocating optional frequency slots to beams. CONSTITUTION:An optional slot is selected among many frequency slots in the up-link of each beam and the frequency slot is connected to an optional beam in down-link. The signal of each beam received by the multi-beam antenna 1 is converted into an intermediate frequency by a broad band receiver and a down converter 2 placed for each beam to cover the entire band. A switch matrix 8 connects the reception signal of each beam to an optional frequency slot of a filter bank 9. The frequency slot selected by the filter bank 9 is connected to a desired beam by a switch matrix 10. Thus, the fluctuation of the communication demand of each beam is covered and a prescribed band is assigned to each beam upon request.
