The first rf module 140 corresponds to the first network mode, that is, the first rf module 140 is a module for transmitting rf signals in a 2G, 3G or 4G network. As shown in fig. 2, the first rf module 140 includes a first rf sub-module 141 and a second rf sub-module 142.

The first rf unit 1411 may be a PA Module integrated Duplexer (PAMID), and since the first rf unit 1411 corresponds to the first rf sub-Module, and the first rf sub-Module is a low frequency band of the first network mode, the first rf unit may be abbreviated as LB PAMID, so that the rf front-end Module may realize a smaller size (saving an area by 35-40mm), and support more functions.

That is, the third radio frequency unit 1511 includes at least a third amplifier, which may be a power amplifier, a third filter, and a third switch. The fourth radio frequency unit 1521 includes at least a fourth amplifier, which may be a power amplifier, a fourth filter, and a fourth switch.
The Power management chip 120 is used to supply Power to the processor 110, and the Power management chip 120 is usually operated in an Average Power Tracking (APT) Power supply mode by the Power management chip 120. The APT power supply mode is a technique of automatically adjusting an operating voltage of a power amplifier in a stepwise manner according to an output power of the power amplifier.
The power supply chip 160 is used to supply power to the first rf module 140, and the power supply chip 160 generally operates in the average power tracking APT power supply mode, but may also operate in the envelope tracking ET power supply mode. The ET supply mode is a technique in which the supply voltage of the power amplifier varies more accurately with the envelope of the input signal. As shown in fig. 2, the power supply chip 160 supplies power to the third rf sub-module 151 and the fourth rf sub-module 152, respectively.
In this embodiment, as shown in fig. 1, when the first rf module 140 is in a working state, the processor 110 controls the power management chip 120 to supply power to the first rf module 140; and/or, in a case that the second radio frequency module 150 is in an operating state, the processor 110 controls the power supply chip 160 to supply power to the second radio frequency module 150 through the transceiver 130.
In an example, when the electronic device operates independently in the 4G network, the first rf module 140 of the electronic device is in an operating state, and the processor 110 controls the power management chip 120 to supply power to the first rf module 140.
In this example, as shown in fig. 2, the first rf module 140 includes a first rf sub-module 141 and a second rf sub-module 142, and in a case that the electronic device operates in a 4G network independently, only the first rf sub-module 141 transmits an rf signal or only the second rf sub-module 142 transmits an rf signal at the same time. That is, in the case that the first rf sub-module 141 transmits an rf signal, the processor 110 controls the power management chip 120 to supply power to the first rf sub-module 141; alternatively, in the case that the second rf sub-module 142 transmits an rf signal, the processor 110 controls the power management chip 120 to supply power to the second rf sub-module 142.
In an example, in a scenario that the electronic device operates in a 5G network independently, that is, the electronic device operates in an independent networking SA, the second rf module 150 of the electronic device is in an operating state, and in a case that the second rf module of the electronic device is in the operating state, the processor 110 controls the power supply chip 160 to supply power to the second rf module 150 through the transceiver 130.
In this example, as shown in fig. 2, the second rf module 150 includes a third rf sub-module 151 and a fourth rf sub-module 152, and only the third rf sub-module 151 transmits an rf signal or the fourth rf sub-module 152 transmits an rf signal at the same time when the electronic device operates in the independent networking SA scenario. That is, in the case that the third rf sub-module 151 transmits rf signals, the processor 110 controls the power supply chip 160 to supply power to the third rf sub-module 151 through the transceiver 130; alternatively, in the case that the fourth rf sub-module 152 transmits an rf signal, the processor 110 controls the power supply chip 160 to supply power to the fourth rf sub-module 152 through the transceiver 130.
In an example, when the electronic device operates in a 4G network and a 5G network simultaneously, that is, the electronic device operates in a non-independent networking NSA scenario, at this time, the first rf module 140 and the second rf module 150 of the electronic device are in an operating state simultaneously, and in a case that the first rf module 140 and the second rf module 150 of the electronic device are in the operating state simultaneously, the processor 110 controls the power management chip 120 to supply power to the first rf module 140 and controls the power supply chip 160 to supply power to the second rf module through the transceiver 130.
In this example, as shown in fig. 2, the first radio frequency module 140 includes a first radio frequency sub-module 141 and a second radio frequency sub-module 142, and the second radio frequency module 150 includes a third radio frequency sub-module 151 and a fourth radio frequency sub-module 152, so that only the first radio frequency sub-module 141 transmits a radio frequency signal or only the second radio frequency sub-module 142 transmits a radio frequency signal at the same time when the electronic device operates in the non-independent networking NSA scenario; and, the third rf sub-module 151 transmits rf signals or the fourth rf sub-module 152 transmits rf signals. That is, in the case that the first radio frequency sub-module 141 or the second radio frequency sub-module 142 transmits a radio frequency signal, the processor 110 controls the power management chip 120 to supply power to the first radio frequency sub-module 141 or the second radio frequency sub-module 142; and, in case that the third rf sub-module 151 or the fourth rf sub-module 152 transmits an rf signal, the processor 110 controls the power supply chip 160 to supply power to the third rf sub-module 151 or the fourth rf sub-module 152 through the transceiver 130.
