Abstract:
A radio frequency radiation module includes a beam forming network capable of applying a signal including contributions to several beams, to several channels. Each channel has a high power amplifier without redundant units, and an antenna radiating feed connected to the output of the amplifier. The beam forming network has a device for selective compensation for failure of one of the channels, increasing the power of the contribution of at least one of the signals to a beam for which the radiation is affected by the failure.
