The working frequency range of the low-frequency signal, the intermediate-frequency signal and the high-frequency signal which can be processed by the signal processing circuit of the MMPA module 10 is 663 MHz-2690 MHz. It can be seen that, the existing MMPA module only integrates circuits supporting low-frequency signal, intermediate-frequency signal and high-frequency signal processing, and with the continuous and commercial use of the fifth generation 5G ultrahigh frequency (e.g., UHB n77(3.3 GHz-4.2 GHz), n78(3.3 GHz-3.8 GHz)) in various countries, the processing of the ultrahigh frequency signal supported by the electronic devices such as mobile phones has become a necessary requirement.

In the current scheme, in order to support the processing capability of the uhf signal, a terminal manufacturer needs to use an additional power amplifier module supporting the uhf signal. Meanwhile, the conventional MMPA module does not consider the situation that the fourth generation 4G radio access network and the fifth generation 5G New air interface NR are connected (E-UTRA and New radio Dual Connectivity, EN-DC) between the low frequency signal, the intermediate frequency signal and the high frequency signal in power supply, and power supplies of the signal processing circuits are connected together. In this case, an additional MMPA module is needed to realize the EN-DC before the low-frequency signal and the intermediate-frequency signal, and before the low-frequency signal and the high-frequency signal.

In view of the above problems, the present application provides an amplifier module, a radio frequency system and a communication device, which will be described in detail below.

As shown in fig. 2, an embodiment of the present invention provides a Multi-band Multi-mode power amplifier (MMPA) module 10, including:

the P port of the SPDT switch 540 is connected to the first filter, one T port of the SPDT switch is connected to the uhf transmission circuit 410, and the other T port is connected to the second uhf reception circuit 420; one P port of the DP4T switch 550 is connected to the coupler, the other P port is configured to be connected to the second filter 620, two T ports of the DP4T switch are configured to be connected to two SRS ports, respectively, and the other two T ports are configured to be connected to a first uhf antenna port 820 for receiving a first uhf receive signal and a second uhf antenna port 830 for a second uhf receive signal, respectively; the target ultrahigh frequency output port and the target ultrahigh frequency input port are any one of the two SRS ports and the two ultrahigh frequency antenna ports.

For example, the SRS port 810 refers to an antenna port for receiving/transmitting an uhf signal, and the symbol "/" indicates an or. The target frequency band signal is a radio frequency signal of a high frequency band.

In a specific implementation, when the fourth selection switch 540 selects to turn on the uhf transmission circuit 410, the fifth selection switch 550 is configured to select to turn on a signal path between the uhf transmission circuit 410 and any one of the two uhf antenna ports and the two SRS ports 810, so as to support a round-robin function of the uhf signals between the antennas. The SRS switching4 antenna transmitting function of the mobile phone is a necessary option of China Mobile communication group CMCC in 'Chinese Mobile 5G Scale test technology white paper _ terminal', and is selectable in the third Generation partnership project 3GPP, and the main purpose is that a base station determines the quality and parameters of 4 channels by measuring uplink signals of 4 antennas of the mobile phone, and then carries out beam forming of a downlink maximized multi-input multi-output Massive MIMO antenna array for the 4 channels according to channel reciprocity, so that the downlink 4x4MIMO obtains the best data transmission performance.

For example, the first and second supply voltages may be less than or equal to 3.6V.

For example, the low frequency signals may include low frequency signals in a 3G, 4G, 5G network, the intermediate frequency signals may include intermediate frequency signals in a 3G, 4G, 5G network, the high frequency signals may include high frequency signals in a 3G, 4G, 5G network, and the ultra high frequency signals may include ultra high frequency signals in a 5G network. The frequency band division of signals of the 2G network, the 3G network, the 4G network and the 5G network is shown in table 1.

TABLE 1

Illustratively, the low-frequency amplification circuit 100 is specifically configured to amplify low-frequency transmission signals of a 3G network, a 4G network, and a 5G network; the intermediate frequency amplifying circuit 200 is specifically configured to amplify intermediate frequency signals of a 3G network, a 4G network, and a 5G network; the high-frequency amplification circuit 300 is specifically configured to amplify high-frequency signals of a 3G network, a 4G network, and a 5G network; the uhf amplifier circuit 400 is specifically configured to amplify an uhf signal of a 5G network.

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 ultrahigh frequency bands which are not available in the 4G network, such as N77, N78, N79 and the like, are added to the 5G network.

For example, the low frequency signals may include low frequency 4G LTE signals and low frequency 5G NR signals. The intermediate frequency signals may include 4G LTE signals at an intermediate frequency and 5G NR signals at an intermediate frequency. The high frequency signals may include high frequency 4G LTE signals and high frequency 5G NR signals. The uhf signal may include a 5G NR signal at an ultrahigh frequency.

the uhf amplification circuit 400 is configured to receive the uhf transmission signal/the first uhf reception signal/the second uhf reception signal at the second supply voltage.

As can be seen, in this example, since the first power supply voltage and the second power supply voltage are independently powered, the MMPA module can simultaneously process the low-frequency transmitting signal and the target frequency band signal, and the target frequency band signal is any one of the intermediate-frequency transmitting signal, the high-frequency transmitting signal, and the ultrahigh-frequency transmitting signal.

In some embodiments, the MMPA module is configured to implement a dual-connection EN-DC function between a fourth generation 4G radio access network and a fifth generation 5G new air interface NR between a non-ultrahigh frequency transmit signal and the ultrahigh frequency transmit signal.

Exemplary, different combinations of EN-DC between the non-uhf transmission signal and the uhf transmission signal are shown in table 2.

TABLE 2

4G LTE frequency band	5G NR frequency band	EN-DC
			LB	MB	LB+MB
LB	HB	LB+HB
			LB	UHB	LB+UHB

Specifically, when the low-frequency amplification circuit and the intermediate-frequency amplification circuit work simultaneously, the EN-DC combination of LB + MB is satisfied; when the low-frequency amplifying circuit and the intermediate-frequency amplifying circuit work simultaneously, the EN-DC combination of LB + HB is met; when the low-frequency amplifying circuit and the ultrahigh-frequency amplifying circuit work simultaneously, the EN-DC combination of LB + UHB is satisfied.

It can be seen that, in the embodiment of the present application, the MMPA module 10 can implement dual transmission processing of multiple signal combinations by independent power supply, thereby improving device capability.
