Referring to fig. 2, the electronic device includes a wireless transceiver unit and at least two radio frequency units, as shown in fig. 2, a radio frequency unit 1 and a radio frequency unit 2 respectively; the radio frequency unit is in communication connection with the wireless transceiver unit, and is configured to send uplink data of the electronic device to a network side (e.g., a base station) and receive downlink data sent by the network side.
The radio frequency unit comprises an Envelope Tracking (ET) power module; in particular, ET technology is a power supply technology that can improve the energy efficiency of a radio frequency power amplifier; the ET technical principle is that a power amplifier of a radio frequency unit operates in a compression region as much as possible, and the power supply voltage of the power amplifier changes along with the envelope of an input signal; the ET technique tracks each power level in the envelope, calculates an optimal voltage for each power point in the envelope, provides a relatively high voltage at the high power point, and provides a relatively low voltage at the low power point, so that each power point has an optimal voltage to reduce the energy of the voltage, thereby achieving the purpose of saving power.
