Device with shared power amplifiers, for use in a wireless telecommunications system
A device with shared power amplifiers for use in a wireless telecommunication System. A plurality of input signals are tapered to alter the phase and/or amplitude distribution between the signals and are then distributed over the input ports of a plurality of power amplifiers. Power amplified replicas of the plurality of input signals are recreated at the output ports of the power amplifiers. The power amplified replicas of the signals are reverse tapered at an output of the device.
