The third amplification module 330 is connected to the first power supply module 110; the fourth amplification module 340 is connected to the second power supply module 120. The first amplification module 310 may be a low frequency power amplification module (LB PAMID/MMPA), the second amplification module 320 may be a medium-high frequency power amplification module (MHB PAMID/MMPA), the third amplification module 330 may be a 4G multi-mode multi-frequency power amplifier (B1/3/39 MMPA), and the fourth amplification module 340 may be a 5G power amplification module (NR PAMID/PA).
The following will describe each part of the rf module 10 provided in the embodiment of the present disclosure in detail:
the first power module 110 and the second power module 120 respectively receive power signals, the first power module 110 is configured to step down the power signals to output first power supply signals, and the second power module 120 is configured to perform envelope processing on the power signals to output second power supply signals.
The first amplification module 310 may include one or more power amplifiers. When the first amplifying module 310 includes a power amplifier, an input terminal of the power amplifier may be connected to the rf generating circuit to receive the rf signal, an output terminal of the power amplifier may be connected to the antenna, for example, an output terminal of the power amplifier may be connected to the antenna through the rf connecting socket, and a power control terminal of the power amplifier is connected to the switching module 210 to receive the first power supply signal output by the first power supply module 110 or the second power supply signal output by the second power supply module 120.
When the first amplifying module 310 includes a plurality of power amplifiers, the plurality of power amplifiers may be connected in series, an input terminal of the first power amplifier is connected to the rf generating circuit to receive the rf signal, an output terminal of the first power amplifier is connected to an input terminal of the second power amplifier, and so on, and an output terminal of the last power amplifier is connected to the antenna, for example, the output terminal of the power amplifier may be connected to the antenna through the rf connecting base. The power control ends of the plurality of power amplifiers are connected to the switch module 210, and in the first frequency band mode, the switch module 210 transmits the first power supply signal to the power control ends of the plurality of power amplifiers; in the second frequency band mode, the switching module 210 transmits a second power supply signal to the power control terminals of the plurality of power amplifiers.
The first amplifying module 310 may have a first band mode and a second band mode, and both the first band mode and the second band mode are low frequency operation modes, for example, the first amplifying module 310 may operate in a band of 600MHz to 900 MHz. The second frequency band mode may be an N28 frequency band, and the frequency of the N28 frequency band is low, so the efficiency of the antenna is low, and therefore the requirement for the transmission power of the first amplifying module is high. The first frequency band may be one or more of the B5, B8, B71, and B82 frequency bands. The input end of the first amplifying module 310 may be provided with a switching module, and the switching module is configured to switch a frequency band of a signal input to the first amplifying module 310.
For example, the maximum voltage that the first power module 110 can output is a first preset voltage, and when the first amplification module 310 operates in the second frequency band mode, the voltage requirement of the power control end of the first amplification module 310 is greater than the first preset voltage, that is, the voltage provided by the first power module 110 cannot meet the requirement of the first amplification module 310 in the second frequency band mode. At this time, the switch module 210 may switch the second power module 120 to supply power to the power control terminal of the first amplification module 310.
As shown in fig. 4, the first amplification module 310 includes: a first power amplifier 311 and a second power amplifier 312, wherein a power control end of the first power amplifier 311 is connected with the switch module 210; the input terminal of the second power amplifier 312 is connected to the output terminal of the first power amplifier 311, and the power control terminal of the second power amplifier 312 is connected to the switch module 210.
As shown in fig. 6, the first power module 110 may include a BUCK function power chip (BUCK function power chip), and the input terminal of the first power module 110 may be connected to a battery of the electronic device, for example, the input terminal of the first power module 110 is directly connected to the battery, or the input terminal of the first power module 110 may be connected to a power management chip, and the power management chip is connected to the battery.
A voltage reduction circuit, such as a BUCK circuit or a charge pump voltage reduction circuit, is disposed in the first power module 110. The input end of the BUCK circuit is connected to the battery or the power management circuit, and the output end of the BUCK circuit is connected to the switch module 210. The BUCK circuit converts the input high voltage signal into a low voltage signal, where the low voltage signal is used for supplying power to the power control terminal of the first amplification module 310 when the first amplification module 310 is in the first frequency band mode. Of course, in practical applications, the first power module 110 may also be provided with a direct connection path, and the direct connection path is used for directly transmitting the power signal to the first amplification module 310.
The input end of the charge pump voltage reduction circuit is connected with the battery or the power management circuit, and the output end of the charge pump voltage reduction circuit is connected with the switch module 210. The charge pump voltage reduction circuit converts an input high voltage signal into a low voltage signal, where the low voltage signal is used for supplying power to the power control terminal of the first amplification module 310 when the first amplification module 310 is in the first frequency band mode. The charge pump step-down circuit can step down the input power supply signal by a multiple.
The second power module 120 may include an envelope tracking function power chip. The input terminal of the second power module 120 may be connected to a battery of the electronic device, or the input terminal of the second power module 120 may be connected to a power management chip of the electronic device, and the power management chip is connected to the battery.
The envelope tracking function power supply chip can provide a power supply signal with proper voltage to the power control end of the power amplification module according to the input signal of the power amplification module. The envelope tracking technology tracks the envelope of a radio frequency signal by adjusting the Power supply voltage of a linear Power amplifier, so that a Power amplification module is located near a peak value of Added Power Efficiency (PAE) as long as possible, and the Efficiency of the linear Power amplifier in a Power back-off area is remarkably improved.
For example, one possible envelope tracking power supply may include a linear regulator including a multi-threshold comparator, a first digital control circuit, and a power transistor unit, and a switching regulator including a second digital control circuit, a driver circuit, a power transistor unit, and an inductor. The first input end of the first digital control circuit is connected with the first output end of the multi-threshold comparator, the first output end of the first digital control circuit is connected with the first input end of the power tube unit, and the second output end of the first digital control circuit is connected with the first input end of the second digital control circuit; the first input end of the driving circuit is connected with the first output end of the second digital control circuit, and the first output end of the driving circuit is connected with the first input end of the power switch tube unit; the first output end of the power switch tube unit is connected with the input end of the inductor.
Since the second power module 120 is an envelope tracking power supply and the output of the second power module 120 is an envelope tracking signal, when the first amplification module 310 operates in the second frequency band mode (the voltage provided by the first power module 110 is insufficient), the power control signal can be provided to the first amplification module 310 through the second power module 120.
The radio frequency module 10 provided by the embodiment of the present disclosure may be used for endec (E-UTRA NR Dual Connectivity, 4G and 5G Dual Connectivity technology) communication. On this basis, the 4G module and the 5G module exist in the rf module 10. In general, the power consumption of the power amplification module (the third amplification module 330) in 4G communication is less than the power consumption of the power amplification module (the fourth amplification module 340) in 5G communication, so that the third amplification module 330 can be supplied with power through the first power supply module 110 with lower cost, and the fourth amplification module 340 can be supplied with power through the second power supply module 120 with the envelope tracking function. When the first amplification module 310 operates in the first frequency band mode, the transmission power is low, and power can be supplied by the first power supply module 110. When the first amplification module 310 operates in the second frequency band mode, the transmission power is high, and power can be supplied by the second power module 120. That is, the first amplifying module 310 uses two power modules necessary for the rf module 10 to supply power in different modes, and no additional power module is needed to supply power, so that the cost of the electronic device can be saved.
For example, the first amplification module 310 may be a low frequency power amplification module (LB PAMID/MMPA), and the operating frequency band of the first amplification module 310 is 600MHz-900 MHz. The second amplifying module 320 may be a medium-high frequency power amplifying module (MHB PAMID/MMPA), and the operating frequency band of the second amplifying module 320 is generally greater than 1.7 GHz. The third amplification module 330 may be a 4G multi-mode multi-frequency power amplification module, the working frequency band of the third amplification module 330 may include B1, B3, B39, etc., and the fourth amplification module 340 may be a 5G new air interface power amplification module (NR PAMID/PA)
It should be noted that, in the embodiment of the present disclosure, the first amplification module 310 may have a plurality of operating frequency bands, the second amplification module 320 may have a plurality of operating frequency bands, and a frequency of any one of the operating frequency bands of the second amplification module 320 is greater than a frequency of any one of the operating frequency bands of the first amplification module 310.

The control module 410 may be a processor of the electronic device or a microprocessor provided in the electronic device, or the like. The control module 410 may detect the current network environment or determine the mode of the first amplification module 310 based on instructions provided by the user. For example, if the control module 410 detects that the operator signal corresponding to the second frequency band mode is strong in the current network environment, it may be determined that the first amplification module 310 needs to operate in the second frequency band mode. Or the control module 410 detects that the operator signal corresponding to the first frequency band mode is strong in the current network environment, it may be determined that the first amplification module 310 needs to operate in the first frequency band mode. Or the control module 410 may determine the operating mode of the first amplification module 310 according to a user instruction, for example, if the control module is used to instruct the electronic device to operate in the 4G mode, the first amplification module 310 may operate in the first frequency band mode, and if the user instructs the electronic device to operate in the 5G mode, the first amplification module 310 may operate in the second frequency band mode.
