Patent ID: 8238814

Claim:
A method of operating a radio frequency radiation module comprising a beam forming network capable of applying a plurality of signals, at least some of which provide contributions to a plurality of beams at respective inputs of a plurality of channels, each of said plurality of channels comprising a high-power amplifier having an adjustable bias point and an antenna feed connected to the output of said high-power amplifier, the method comprising: detecting a failure of one of said plurality of channels; identifying beams affected by said failure, and determining a corresponding loss of EIRP; identifying the remaining plurality of channels contributing to said affected beams; increasing the contributions of at least some of said remaining plurality of channels to said affected beams in order to compensate for said loss of EIRP; and adjusting the bias points of the high-power amplifiers of said remaining plurality of channels in order to provide an increase in required output power.
