ELECTRONIC DEVICE INCLUDING CONVERGED POWER AMPLIFIER AND METHOD FOR OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18634249 titled 'ELECTRONIC DEVICE INCLUDING CONVERGED POWER AMPLIFIER AND METHOD FOR OPERATING THE SAME
According to an embodiment, an electronic device may comprise memory storing instructions, a first power amplifier (PA) selectively connected to at least one of a plurality of modulators through a first switch, a first modulator including a second switch connected between the first switch and a first capacitor and a third switch connected to an output end of a first buck converter and being among the plurality of modulators configured to selectively operate in an envelope tracking (ET) mode or an average power tracking (APT) mode, a second modulator including a fourth switch connected between the first switch and a second capacitor and a fifth switch connected to an output end of a second buck converter and being among the plurality of modulators configured to selectively operate in the ET mode or the APT mode, and at least one processor, comprising processing circuitry, operatively connected to the first PA, the first modulator, and the second modulator. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to: control the first modulator to operate in the APT mode based on identifying a first event associated with network communication, control the first switch to connect the first PA to the first modulator and the second modulator; control the second switch, the third switch, and the fourth switch to turn on; and control the fifth switch to turn off based on the first modulator operating in the APT mode.
