A first power supply module 10, configured to provide a preset first power supply voltage; and a second power supply module 20, configured to provide a preset second power supply voltage, where the second power supply voltage is smaller than the first power supply voltage.

The first rf module 30 is connected to the first power supply module 10 and the rf transceiver 50, respectively, and configured to perform power amplification on the received first high-frequency signal of the first network under the action of the first power supply voltage.

The second rf module 40 is configured with a first power supply port VCC1 connected to the first power supply module 10, a second power supply port VCC2 connected to the second power supply module 20, and a first input port PA IN1 and a second input port PA IN2 connected to the rf transceiver 50. The second rf module 40 includes a first transmit amplifying unit 401 and a second transmit amplifying unit 402. A first transmitting and amplifying unit 401, respectively connected to the first power supply port VCC1 and the first input port PA IN1, for performing power amplification on a received second high-frequency signal of the first network under the action of the first power supply voltage, where a frequency range of the second high-frequency signal is lower than a frequency range of the first high-frequency signal; the second transmitting and amplifying unit 402 is respectively connected to the second power supply port VCC2 and the second input port PA IN2, and configured to perform power amplification on the received first preset frequency band signal of the second network under the action of the second power supply voltage, where a frequency range of the first preset frequency band signal is lower than a frequency range of the second high-frequency signal. The radio frequency module is used for simultaneously outputting a first high-frequency signal, a second high-frequency signal and a first preset frequency band signal which are subjected to power amplification.

The first power supply module 10 is configured to provide a first power supply voltage, and specifically, the first power supply module 10 is connected to the first rf module 30 and the first transmit amplifying unit 401 of the second rf module 40 to output the first power supply voltage. The first Power supply module 10 may include, for example, a Power Management IC (PMIC) connected to a battery to supply Power of the battery to the first and

second rf modules

30 and 40. The second power supply module 20 is configured to provide a second power supply voltage, and specifically, the second power supply module 20 is connected to the second transmitting and amplifying unit 402 of the second radio frequency module 40 to output the second power supply voltage. The second power supply module 20 may include, for example, a PMIC connected to a battery to supply power from the battery to the second rf module 40.

The first supply voltage is greater than the second supply voltage, and the first supply voltage can support the power supply of the first transmit amplification unit 401 of the first radio frequency module 30 and the second radio frequency module 40, which have a greater output power requirement, so as to ensure the radio frequency performance of the first transmit amplification unit 401 of the first radio frequency module 30 and the second radio frequency module 40; the second supply voltage may support the power supply of the second transmitting and amplifying unit 402 of the second rf module 40 with smaller output power requirement, and ensure the power supply of the second transmitting and amplifying unit 402 of the second rf module 40. Optionally, the first power supply module 10 and the second power supply module 20 are respectively connected to the radio frequency transceiver 50, and correspondingly output a first power supply voltage and a second power supply voltage according to a control command of the radio frequency transceiver 50. Specifically, the radio frequency transceiver 50 may monitor the operating states of the first radio frequency module 30 and the second radio frequency module 40 by respectively obtaining the input power and the coupling signal of the output terminal of the first radio frequency module 30 and the second radio frequency module 40, and then control the first power supply module 10 and the second power supply module 20 to adjust the power supply voltage according to the operating states.

The first network may be a 5G network, and the Radio frequency signal of the first network may be referred to as a New Radio (NR) signal, that is, a 5G NR signal. The second network may be a 4G network, and the radio frequency signal of the second network may be referred to as a Long Term Evolution (LTE) signal, that is, a 4G LTE signal. Correspondingly, the first high-frequency signal and the second high-frequency signal of the first network are both 5G NR signals, and the first preset frequency band signal of the second network is a 4G LTE signal.

Wherein, the frequency range of the second high frequency signal is lower than that of the first high frequency signal, it can be understood that the first high frequency signal is a 5G NR ultrahigh frequency signal, such as a 5G NR N78 signal; the second high frequency signal is a 5G NR high frequency signal, such as 5G NR N40, N41 signal. The frequency range of the first preset frequency band signal is lower than the frequency range of the second high frequency signal, and the first preset frequency band signal can be understood as a 4G LTE intermediate frequency signal or a 4G LTE low frequency signal.

The frequency division of the low-frequency signal, the intermediate-frequency signal, the high-frequency signal and the ultrahigh-frequency signal is shown in table 1.

TABLE 1 frequency band division table for low frequency signal, intermediate frequency signal, high frequency signal and ultrahigh frequency signal

It should be noted that, in the 5G network, only the identifier before the sequence number is changed along with the frequency band used by 4G. In addition, some super high frequency bands which are not available in the 4G network are added to the 5G network, for example, N77, N78, N79, and the like.

The first rf module 30 is connected to the first power supply module 10 and the rf transceiver 50, respectively, a first rf path is formed between the first rf module 30 and the rf transceiver 50, and a first network first high-frequency signal sent by the rf transceiver 50 is power-amplified by a first power supply voltage and then output to an antenna (e.g., ANT0 in fig. 1); the second rf module 40 is connected to the first power supply module 10, the second power supply module 20, and the rf transceiver 50, a second rf path and a third rf path are formed between the second rf module 40 and the rf transceiver 50, the first rf path, the second rf path, and the third rf path are respectively connected to one antenna (e.g., ANT1 and ANT2 in fig. 1) in a one-to-one correspondence, and the rf module can output three signals with different networks simultaneously to support amplification of the 4G LTE signal and the 5G NR signal, thereby realizing dual connection of the 4G LTE signal and the 5G NR signal.

Specifically, the path in which the first rf module 30 is located is a first rf path; the second rf module 40 includes a first transmit amplifying unit 401 and a second transmit amplifying unit 402, the first transmit amplifying unit 401 is respectively connected to the first power supply port VCC1 and the first input port PA IN1, and the rf transceiver 50, the first input port PA IN1 and the first transmit amplifying unit 401 are IN a second rf path; the second transmitting and amplifying unit 402 is connected to the second power supply port VCC2 and the second input port PA IN2, respectively, and the radio frequency transceiver 50, the second input port PA IN2 and the second transmitting and amplifying unit 402 are IN a third radio frequency path.

The first path of signal is a first high-frequency signal power-amplified by the first rf module 30, and may be an ultra-high frequency signal of a first network; the second path of signals is a second high-frequency signal power-amplified by the first transmitting and amplifying unit 401 of the second radio frequency module 40, and may be a high-frequency signal of the first network; the third signal is a first preset frequency band signal power-amplified by the second transmitting and amplifying unit 402 of the second rf module 40, and may be an intermediate frequency signal or a low frequency signal of the second network. Therefore, the combination of the first signal, the second signal and the third signal can satisfy the configuration requirements of different EN-DC combinations (e.g., EN-DC combinations of L/MB + N41 and L/MB + N78) between the 4G LTE signal and the 5G NR signal, as shown in table 2.

Table 2 is a table of different EN-DC combination configurations between 4G LTE signal and 5G NR signal in an embodiment

4G LTE frequency band	5G NR frequency band	EN-DC
			L	H；UH	L+H；L+UH
M	H；UH	M+H；M+UH

Specifically, as shown in table 2, when the first preset frequency band signal is a 4G LTE low-frequency signal, the EN-DC combination of L + H and L + UH is satisfied; and when the first preset frequency band signal is a 4G LTE intermediate frequency signal, the EN-DC combination of M + H and M + UH is met.

Optionally, the first transmit amplifying unit 401 can also support power amplification on a third high-frequency signal of the second network, where a frequency band of the third high-frequency signal is the same as a frequency band of the second high-frequency signal; the second transmitting and amplifying unit 402 can also support the rf signal of the first network with the same frequency band as the first predetermined frequency band signal. For example, when the first preset frequency band signal is a 4G LTE low frequency signal, the second transmit amplifying unit 402 may further support power amplification on a 5G NR low frequency signal to implement NRCA combination of a 5G network. For example, when the first preset frequency band signal is a 4G LTE intermediate frequency signal, the second transmitting and amplifying unit 402 may further support power amplification on a 5G NR intermediate frequency signal to implement NRCA combination of a 5G network.

Wherein, optionally, the first radio frequency module 30 may be understood as including a Power Amplifier (PA), or a Multi-band Multi-mode Power amplifier (MMPA) integrating a plurality of Power amplifiers to achieve Power amplification of the first high frequency signal (5G NR uhf signal) of the first network; the power amplifier module can also be understood as an LPAF (LNA-PA ASM module with integrated filter) to realize the functions of low noise amplification, filtering and the like while realizing power amplification, and the LPAF is an independent integrated device, which is beneficial to the miniaturization of the radio frequency module.

The first transmit amplifier unit 401 and the second transmit amplifier unit 402 may be understood as a single Power Amplifier (PA), or may also be understood as a Multi-band Multi-mode Power amplifier (MMPA) integrating a plurality of Power amplifiers, and the second rf module 40 may be understood as a Power amplifier module (PA Mid) integrating a duplexer, or may be a PA Mid with a built-in low noise amplifier, that is, an L-PA Mid. Each port configured on the second rf module 40 may be understood as an rf pin of a PA Mid device or an L-PA Mid device. For convenience of illustration, the second rf module 40 is a phase 7MHB L-PAMID device. The second rf module 40 integrates a medium-high frequency power amplifier MHB PA, a medium-high frequency low noise amplifier MHB LNA, a duplexer, a filter, a coupler, and a switch. The second rf module 40 can implement WCDMA, 4G LTE signals of the mid-high band 3G cellular network and transceiving of the frequency recombination NR band, for example, receiving and transmitting processing of the N41 frequency band.

The inventor of the present invention has found through creative work that, in the related art, in order to implement the dependent networking operating mode of the EN-DC framework between the second high frequency signal of the first network and the first preset frequency band signal of the second network, the sending and receiving processing of the second high frequency signal of the first network is usually implemented by using an independent external LPAF (LNA-PA ASM module with integrated filter, power amplifier switch module integrated with filter and low noise amplifier), the LPAF device is expensive, for example, 1.2 dollars, and the supplier is a first-line manufacturer, and the supply resource is tight, which limits the wide application of the radio frequency module. In this embodiment, the first transmitting and amplifying unit 401 and the second transmitting and amplifying unit 402 are integrated in the second rf module 40, so that the second rf module 40 can simultaneously support the amplifying function of the second high-frequency signal and the first preset frequency band signal, the occupied area of the rf module is reduced, the miniaturization of the rf module is facilitated, the number of independent external LPAFs can be reduced, and the cost is reduced.

In the above embodiment, the first power module 10 is configured to supply power to the first rf module 30 and supply power to the first transmitting and amplifying unit 401 of the second rf module 40, and the second power module 20 is configured to supply power to the second transmitting and amplifying unit 402 of the second rf module 40, so that the first transmitting and amplifying unit 401 and the second transmitting and amplifying unit 402 of the first rf module 30 and the second rf module 40 operate simultaneously. Therefore, the radio frequency module can simultaneously output the first high-frequency signal, the second high-frequency signal and the first preset frequency band signal which are subjected to power amplification, and a non-independent networking working mode of the EN-DC framework is realized.

Optionally, the operation mode of the first power supply module 10 is an Envelope Tracking (ET) power supply mode to provide the first power supply voltage, and the first power supply module 10 may track a power amplitude (Envelope) of a radio frequency signal output by a powered module, and change a magnitude of the provided first power supply voltage according to the power amplitude (Envelope). The operating mode of the second Power supply module 20 is an Average Power Tracking (APT) Power supply mode to provide a second Power supply voltage, and the second Power supply module 20 may track an Average Power amplitude of the radio frequency signal output by the powered module, and correspondingly change the magnitude of the second Power supply voltage according to the Average Power amplitude. Wherein, the output voltage of the first power supply module 10 in the ET power supply mode is greater than the input voltage thereof; the output voltage of the second power supply module 20 in the APT power supply mode is less than or equal to its input voltage.

Compared with the APT power supply mode, the first power supply module 10 in the ET power supply mode has a boosting function, and the output first power supply voltage is higher, so that the radio frequency performance of the first high frequency signal of the first radio frequency module 30 and the second high frequency signal of the second radio frequency module 40 can be ensured; compared with the ET power supply mode, the second power supply module 20 in the APT power supply mode does not have a boosting function, and outputs a lower second power supply voltage, but because the frequency band of the first preset frequency band signal is lower than the second high-frequency signal, the second power supply voltage is lower than the first power supply voltage, but the transmission requirement of the first preset frequency band signal of the second radio frequency module 40 can be met to ensure the radio frequency performance of the first preset frequency band signal.

The inventor finds, through creative work, that in the related art, in order to support the non-independent networking operation mode of the EN-DC framework and the transceiving of high-frequency signals and ultrahigh-frequency signals in the 5G NR, different radio frequency channels generally need to adopt a plurality of relatively independent power supply modules supporting the ET power supply mode for supplying power. On one hand, the power supply modules in the ET power supply mode are expensive in cost, for example, some power supply modules need about 1.5 dollars, while the power supply modules in the APT power supply mode are low in cost, and the price difference of each power supply module is about 1.3 dollars; on the other hand, the power supply modules between different radio frequency paths are relatively independent, which results in that the radio frequency architecture needs to occupy more space and is not favorable for the space layout problem of the radio frequency architecture.

In the embodiment of the present application, by combining the setting conditions of the first radio frequency module 30 and the second radio frequency module 40 and the EN-DC architecture combination requirement, and by combining the first power supply module 10 in the ET power supply mode and the second power supply module 20 in the APT power supply mode, the number of power supply modules in the ET power supply mode can be reduced and the cost can be reduced on the basis of meeting the radio frequency performance of the first radio frequency module 30 and the second radio frequency module 40 and the EN-DC architecture combination requirement.

The rf module provided in this embodiment includes a first power module 10, a second power module 20, a first rf module 30, and a second rf module 40, where the second rf module 40 includes a first transmitting and amplifying unit 401 and a second transmitting and amplifying unit 402. The first power supply module 10 is configured to provide a preset first power supply voltage; the second power supply module 20 is configured to provide a preset second power supply voltage; the first radio frequency module 30 is configured to perform power amplification on a received first high-frequency signal of the first network under the action of the first supply voltage; the first transmitting and amplifying unit 401 is configured to perform power amplification on the received second high-frequency signal of the first network under the action of the first power supply voltage; the second transmitting and amplifying unit 402 is configured to perform power amplification on a received first preset frequency band signal of the second network under the action of the second power supply voltage, where a frequency range of the first preset frequency band signal is lower than a frequency range of the second high-frequency signal. Therefore, the radio frequency module can simultaneously output the first high-frequency signal subjected to power amplification, the second high-frequency signal and the first preset frequency band signal so as to support the non-independent networking working mode of the EN-DC framework. By integrating the first transmitting and amplifying unit 401 and the second transmitting and amplifying unit 402 in the second radio frequency module 40, the second radio frequency module 40 can simultaneously support the amplifying and processing functions of the second high-frequency signal and the first preset frequency band signal, so that the occupied area of the radio frequency module is reduced, the number of independent plug-in LPAFs can be reduced, and the cost is reduced; the first power supply module 10 supplies power to the first rf module 30 and the first transmitting and amplifying unit 401 at the same time, and the second power supply module 20 supplies power to the second transmitting and amplifying unit 402, so that the cost can be reduced on the basis of meeting the radio frequency performance and EN-DC architecture combination requirements of the first rf module 30 and the second rf module 40.

Optionally, the first gating unit 403 is connected to the radio frequency transceiver 50, and the radio frequency transceiver 50 controls the gating path of the first gating unit 403 according to the configuration information of the antenna, the radio frequency receiving information, and the like.

Through the first gating unit 403, the filtering paths between the first filtering unit 403 and the first antenna and between the second filtering unit 404 and the second antenna can be selectively turned on, so that the uplink signal is distributed on the antenna with better antenna efficiency, and the communication performance of the radio frequency system is further improved.

The number of the first filtering units 404 and the number of the second filtering units 405 may be multiple, when the number of the first filtering units 404 and the number of the second filtering units 405 are multiple, the multiple first filtering units 404 may be connected to the first transmitting and amplifying unit 401 through a single-pole multi-throw switch, the multiple second filtering units 405 may be connected to the second transmitting and amplifying unit 402 through a single-pole multi-throw switch, and the first gating unit 403 may selectively turn on radio frequency paths between the multiple first filtering units 404 and the first antenna, and selectively turn on radio frequency paths between the multiple second filtering units 405 and the second antenna.
