Abstract:
A method and telecommunication device in which the telecommunication device is provided with multiple antennas and power amplifiers to provide a beamformed transmit stage. An envelope tracking circuit helps achieve significant power savings in the power amplifier and can be used to provide the power supply for the multiple power amplifiers. A single envelope tracking power supply may be used to produce the supply voltage to the individual power amplifiers that operate on the transmit signal and its phase shifted variant. Accordingly, the user equipment experiences the benefits of both reduced power consumption using the envelope tracker and beam formed transmission.
