Fig. 1 is a block diagram of an rf module according to an embodiment, and referring to fig. 1, in this embodiment, the rf module includes at least two power modules 10, at least two transmitting groups 20, and a power supply control circuit 30.

Each transmitting group 20 includes at least two power amplifying modules 210, each power amplifying module 210 is switchably connected to any one of the at least two power modules 10 in a conducting manner, and each power amplifying module 210 in the same transmitting group 20 is configured to amplify power of a received radio frequency signal under the power supply action of the same power module 10 (fig. 1 only shows the connection condition of the power module 10 when the power amplifying module 210 in each transmitting group 20 is connected in a conducting manner, but does not show the connection condition of other power modules 10 when the power amplifying module 210 is disconnected from the power amplifying module); the power supply control circuit 30 is configured to determine an abnormal power supply module and an abnormal emission group that is in conductive connection with the abnormal power supply module according to an operation mode of at least two power supply modules, identify an abnormal power amplification module from the abnormal emission group, and control the normal power amplification module in the abnormal emission group to be switched from conductive connection with the abnormal power supply module to conductive connection with a target power supply module, where the target power supply module is any one of the at least two power supply modules except the abnormal power supply module.

The number of the transmitting groups 20 is at least two, and each transmitting group 20 includes at least two power amplifying modules 210, so that the radio frequency module includes a plurality of power amplifying modules 210, and the power amplifying modules 210 can form a plurality of transmitting paths, so that the radio frequency module supports multipath transmitting processing, and communication quality and user experience are improved. Alternatively, the power amplification modules 210 may be grouped according to whether the radio frequency signals received by the power amplification modules 210 are in the same transmission path group in practical application, and the power amplification modules 210 connected to the same transmission path group may be assigned to the same transmission group 20. Optionally, the frequency bands of the radio frequency signals supporting power amplification may be grouped according to the requirement, for example, the partial power amplification modules 210 of the low frequency band, the intermediate frequency band and the high frequency band are divided into the same emission group 20, and the partial power amplification modules 210 of the high frequency band and the ultrahigh frequency band are divided into the same emission group 20 to support different frequency band combinations; the power amplifying modules 210 may be grouped according to their power supply requirements, for example, different power amplifying modules 210 with power supply requirements close to each other may be divided into the same transmitting group 20. It should be noted that, the present embodiment is not limited to the aforementioned grouping method, and may be specifically set according to actual requirements.

Each power amplification module 210 is switchably connected to any one of the at least two power modules 10, and each power amplification module 210 in the same transmitting group 20 is configured to amplify power of a received radio frequency signal under the power supply of the same power module 10. Typically, in the case where each power amplifying module 210 in each transmitting group 20 is normally powered, the power module 10 of each power amplifying module 210 in a different transmitting group 20 is different by default.

Each Power amplification module 210 may include one or more Power Amplifiers (PA), where a Power supply terminal of each PA is switchably connected to at least two Power modules 10, an input terminal of each PA is used for being connected to a radio frequency transceiver to receive radio frequency signals, an output terminal of each PA is used for being connected to an antenna or other radio frequency front end module, and when connection between the PA and the Power modules 10 is turned on, the PA performs Power amplification on the received radio frequency signals, and outputs the radio frequency signals after Power amplification to the antenna for the antenna to transmit outwards. Alternatively, the power supply control circuit 30 may include a radio frequency transceiver, and when the power supply control circuit 30 includes the radio frequency transceiver, the power supply control circuit 30 may be connected to an input terminal of each power amplification module 210 to provide a radio frequency signal to each power amplification module 210 (fig. 1 illustrates connection of the power supply control circuit 30 to each power amplification module 210, for example).

Optionally, the power amplification module 210 may also include other functional devices to implement other auxiliary functions, for example, a low noise amplifier to implement the receiving function at the same time. When the power amplification module 210 further includes a Low noise amplifier, the power amplification module 210 may be a Low frequency power amplifier module (LB L-PA Mid, low Band PAMID WITH LNA) with built-in Low noise amplifier, or may be a middle-high frequency power amplifier module (MHB L-PA Mid, MIDDLE AND HIGH Band PAMID WITH LNA) with built-in Low noise amplifier; the power amplifier switching module (LPAF, LNA-PAASM module WITH INTEGRATED FILTER) may be integrated with a filter and a low noise amplifier, for example, the LPAF may support a high frequency signal or an ultra high frequency signal.

The number of the power modules 10 is at least two, each power module 10 may be connected to each power amplification module 210 in the same transmitting group 20, or may be connected to a plurality of power amplification modules 210 in different transmitting groups 20, and when the connection between the power module 10 and the power amplification module 210 is turned on, the power module 10 provides a power supply signal to the power amplification module 210 that is turned on and connected, so that the power amplification module 210 performs power amplification on the received radio frequency signal. Optionally, the power module 10 may perform voltage adjustment according to the frequency band of the radio frequency signal that the power amplification module 210 needs to support power amplification, so as to output a power supply signal suitable for the normal operation of the power amplification module 210, so as to meet the requirement of the user. The Power module 10 may include, for example, a battery and a Power management chip (Power MANAGEMENT IC, PMIC) connected to the battery to adjust the Power of the battery and provide the adjusted Power to the Power amplification module 210.

In the power amplification module 210, PA belongs to a high-power device, and is often in a high-temperature, high-power and high-current working scene, a small-probability burning event may occur, and after the power amplifier is burned, a power line short circuit may occur in the power amplification module 210, so that the power amplification module 210 is in an abnormal working state, which may cause that other power amplification modules 210 powered by the same power module 10 cannot work normally. In this embodiment, the power module 10 is configured to be capable of operating in different operation modes, and in the case that an abnormality occurs in the power amplification module 210 in the emission group 20 to which the power module 10 is connected in a conductive manner, the power module 10 is switched to an operation mode having a protection function, for example, the power module 10 may be switched to an operation mode having an OCP (Over Current Protection, over-current protection) function, the operation mode having the protection function is defined as an abnormal operation mode, the power module in the abnormal operation mode is defined as an abnormal power module, and the emission group 20 supplied by the abnormal power module is defined as an abnormal emission group.

When the power supply control circuit determines the abnormal power supply module and the abnormal emission group connected with the abnormal power supply module in a conducting manner, the abnormal power amplification module can be identified from the abnormal emission group by switching the power supply modules of the power amplification modules 210 in the abnormal emission group. Specifically, during the switching process of the power supply module 10, when the abnormal power amplification module is connected with any power supply module in a conducting manner, any power supply module is in an abnormal working mode; when the normal power amplification module is connected with any one of the power modules 10 except the abnormal power module in a conducting manner, the other any one of the power modules 10 can be kept in a normal working mode. The abnormal power amplification module and the normal power amplification module may be directly determined by the power supply control circuit 30, or may be determined by other modules and fed back to the power supply control circuit 30.

The power supply control circuit 30 determines an abnormal power supply module and an abnormal emission group according to the working modes of the power supply modules 10, identifies an abnormal power amplification module from the abnormal emission group, and controls the normal power amplification module in the abnormal emission group to be switched from the connection with the abnormal power supply module to the connection with the target power supply module so as to ensure that the normal power amplification module can keep working normally, and improves the number of frequency bands which can be used by the radio frequency module after the power amplification module 210 is burnt out, so that user experience is improved, and the passenger withdrawal rate is reduced. It will be appreciated that in other embodiments, some of the plurality of transmit groups may include only one power amplification module, and the power control circuit 30 may not perform the operation associated with switching the power module 10 when the abnormal transmit group includes only the abnormal power amplification module.

Alternatively, the power supply control circuit 30 obtains the working mode of each power supply module 10, and the power supply control circuit 30 may be connected to each power supply module 10 to actively or passively obtain the working mode of each power supply module 10; an auxiliary detection circuit may be provided between the power supply control circuit 30 and the power supply module 10 to acquire an operation mode by the auxiliary detection circuit and inform the power supply control circuit 30.

The radio frequency module provided in this embodiment includes at least two power modules 10, at least two emission groups 20 and a power supply control circuit 30, the power supply control circuit 30 determines an abnormal power module and an abnormal emission group according to the working mode of each power module 10, identifies an abnormal power amplification module from the abnormal emission group, and controls the normal power amplification module in the abnormal emission group to be switched from the connection with the abnormal power module to the connection with the target power module, so that the normal power amplification module can be ensured to keep working normally, the number of frequency bands which can be used by the radio frequency module after the power amplification module 210 burns out is increased, so as to improve user experience, and reduce the guest-back rate.

In some embodiments, as shown in fig. 2, the rf module further includes a switch module 40, and the power supply control circuit 30 controls the conduction condition of the connection between each power amplifying module 210 and the power module 10 by controlling the conduction condition of the switch module 40.

The switch module 40 is connected to the power supply control circuit 30 through a controlled end, is correspondingly connected to the power supply modules 10 through a plurality of first ends, and is correspondingly connected to the power amplification modules 210 through a plurality of second ends, so that the switch module 40 switches the power supply modules 10 to the power amplification modules 210 of the abnormal emission group under the control of the power supply control circuit 30 to determine an abnormal power amplification module and a normal power amplification module; and switching the normal power amplification module from the connection with the abnormal power supply module to the connection with the target power supply module.

Optionally, the connection between the default power module 10 and each power amplification module 210 may be selected, and when each power amplification module 210 is in a normal working state, the switch module 40 connects each power amplification module 210 to the default power module 10, so that each default power module 10 supplies power to the transmitting group 20 with default connection; when the default power module 10 is in the abnormal working mode, the switch module 40 turns off the connection between the default power module 10 and the normal power amplification module in the abnormal emission group, and simultaneously turns on the connection between the normal power amplification module and any one power module 10 except the abnormal power module in at least two power modules, and the power module 10 does not supply power to the abnormal emission group.

The power supply control circuit 30 and the switch module 40 can timely switch the power supply module 10 to the normal power amplification module in the abnormal emission group when the power supply module 10 is in the abnormal working mode, so that the normal work of the normal power amplification module is ensured.

In some embodiments, the switching module 40 is further configured to disconnect the abnormal power amplification module from the abnormal power supply module under the control of the power supply control circuit 30.

When the PA inside the power amplification module 210 burns out, an abnormal large current is generated on the power supply path between the abnormal power amplification module and the power supply module 10 that is connected in an original conduction manner, and when the power supply control circuit 30 determines an abnormal emission group according to the working mode of the power supply module 10, the switch module 40 is controlled to disconnect the abnormal power amplification module from the abnormal power supply module in the abnormal emission group, so that the power amplification module 210 can be prevented from continuously generating an abnormal large current, and serious heating conditions can be avoided.

In some embodiments, as shown in fig. 2, the switch module 40 includes: a plurality of switching units 410.

Each of the switch units 410 has a controlled end, at least two first ends and a second end (two first ends and one second end are illustrated in fig. 2 as examples), the at least two first ends of each of the switch units 410 are respectively connected with at least two power modules 10 correspondingly, and the second end of each of the switch units 410 is connected with a power amplifying module 210 correspondingly; the power supply control circuit 30 is configured with a plurality of control interfaces, each control interface is connected with a controlled end of a switch unit 410, and the power supply control circuit 30 is configured to send a first control signal to each switch unit 410 corresponding to an abnormal emission group, so as to instruct each switch unit 410 to conduct connection between the corresponding connected power amplification module 210 and another arbitrary power module 10, so as to identify an abnormal power amplification module from the abnormal emission group; and the second control signal is further sent to each switch unit 410 correspondingly connected to the normal power amplification module after the abnormal power amplification module is identified, so as to control each switch unit 410 to conduct the connection between the normal power amplification module and the target power module.

The switch unit 410 is disposed on a connection path between each power amplifying module 210 and the power module 10, and by controlling the on condition of the switch unit 410, the power supply condition of the power module 10 to each power amplifying module 210 can be controlled, and by controlling the power supply condition of the power module 10, the normal power amplifying module and the abnormal power amplifying module of the abnormal emission group can be determined according to the working mode of the power module 10, and on the other hand, the power supply of the normal power amplifying module can be updated by switching the power module 10. The first control signal and the second control signal respectively include a turn-on signal and a turn-off signal, the turn-on signal is used for controlling the switch unit 410 to turn on the connection path which is originally in the turn-off state, and the turn-off signal is used for controlling the switch unit 410 to turn off the connection path which is originally in the turn-on state.

After the power supply control circuit 30 determines the abnormal emission group, a first control signal may be sent to each switch unit 410 corresponding to each power amplification module 210 of the abnormal emission group, so that the switch units 410 respectively switch the power modules 10 corresponding to the power amplification modules 210, so as to determine a normal power amplification module and an abnormal power amplification module according to the operation mode of the switched power modules 10. The embodiment of determining the normal power amplifying module and the abnormal power amplifying module according to the working mode of the switched power module 10 is referred to the above embodiment, and will not be described herein. Alternatively, the first control signal may be sequentially sent to each of the switch units 410 corresponding to each of the power amplification modules 210 of the abnormal emission group, respectively, so as to sequentially determine whether each of the power amplification modules 210 is abnormal according to the switching result of the switch units 410.

When the power supply control circuit 30 determines the normal power amplification module, a second control signal may be sent to each of the switch units 410 corresponding to the normal power amplification module, so that the switch units 410 disconnect the normal power amplification module from the power module 10 in the abnormal operation mode, and simultaneously connect the normal power amplification module with the target power module.

When the power supply control circuit 30 determines the abnormal power amplification module, a third control signal may be transmitted to each of the switching units 410 corresponding to the abnormal power amplification module, so that the switching units 410 disconnect the abnormal power amplification module from the abnormal power supply module, respectively.

By providing a plurality of switch units 410, each switch unit 410 is provided on a connection path between each power amplification module 210 and the power module 10, so that the on/off state of each switch unit 410 can be independently controlled, and the power module 10 can be switched more accurately.

Taking the abnormal working mode as the OCP overcurrent protection working mode, the power supply control circuit 30 as the radio frequency transceiver and the control interface as the GPIO interface as an example, when the radio frequency transceiver obtains that the working mode of the power module 10 is in the abnormal working mode, the radio frequency transceiver sequentially sends the first control signal to each switch unit 410 through the GPIO interface to switch the power module 10, and judges the normal power amplifying module and the abnormal power amplifying module through the working mode of the power module 10 in the switching process, and after judging the normal power amplifying module and the abnormal power amplifying module, the second control signal is sent through the GPIO interface to control the switch unit 410 to switch the power of the normal power amplifying module.

Alternatively, each of the switch units 410 includes at least one switch device, which may be, for example, a single-pole multi-throw switch, for example, when the power amplifying module 210 is connected to the two power modules 10, the switch unit 410 may be a single-pole double-throw switch, where two first ends of the single-pole double-throw switch are respectively connected to the output ends of the two power modules 10, and a second end of the single-pole double-throw switch is connected to the power supply end of the power amplifying module 210. A single pole double throw switch can be configured to conduct the connection between one power module 10 and the power amplification module 210 by default and disconnect the connection between the other power module 10 and the power amplification module 210; when the power supply control circuit 30 obtains that the power supply module 10 which is connected in a conducting manner is in an abnormal working mode, the single-pole double-throw switch disconnects the connection between the normal power amplification module and the abnormal power supply module in the abnormal emission group, and the connection between the normal power amplification module and the target power supply module is conducted, so that the switching of the power supply module 10 is realized.

Taking the abnormal working mode as an OCP overcurrent protection working mode, the radio frequency transceiver as the power supply control circuit 30, the mipi interface as the state feedback interface and the mipi signal as the detection interface of the power supply control circuit 30, the radio frequency transceiver and the power module 10 are in communication through mipi signal connection, and the working mode of the power module 10 can be actively or passively acquired through mipi signals. Specifically, when the PA of a certain power amplification module 210 in each transmitting group 20 is burned to cause a short circuit of its power supply path, the power module 10 is triggered to enter the OCP overcurrent protection working mode by a large current generated by the short circuit, and the radio frequency transceiver actively reads the working mode of the power module 10 through the mipi interface with the power module 10, or the power module 10 actively feeds back the change of the working mode thereof, so that the radio frequency transceiver knows the working mode of the power module 10.

Alternatively, the power module 10 may generate a status signal with a status flag bit change according to the current operation mode, for example, when the operation mode is detected to be in the abnormal operation mode, generate a pull-up or pull-down level signal, where the pull-up or pull-down level signal is used to indicate to the power supply control circuit 30 that the current operation mode is in the abnormal operation mode, and the currently powered emission group 20 is an abnormal emission group.

Optionally, a power supply circuit, a detection circuit, a mode switching circuit, and the like may be disposed inside the power supply module 10, where the detection circuit may be a voltage detection circuit, a current sampling circuit, and the like, an output end of the power supply circuit is connected to an output interface of the power supply module 10, an output end of the mode switching circuit is connected to a state feedback interface of the power supply module 10, the power supply circuit may be used to supply power to the power amplification module 210, and the detection circuit is used to obtain a power supply parameter on a power supply path between the output end of the power supply circuit and the power amplification module 210, and notify the mode switching circuit to perform switching of an abnormal working mode when the power supply parameter meets an overcurrent mode parameter condition, and generate a state signal to characterize a current working mode.

In this embodiment, by configuring the interfaces of the power module 10 and the power supply control circuit 30, the two are directly communicated through the interfaces, so as to quickly obtain the working mode of the power module 10, thereby improving the effectiveness and timeliness of power supply control and improving the user experience.

In some embodiments, the power supply control circuit 30 is further configured to obtain a target frequency band of the radio frequency signal supported by the abnormal power amplification module for power amplification; and updating the available network searching frequency band according to the target frequency band, wherein the available network searching frequency band is a frequency band of the radio frequency module for supporting radio frequency signal transmission in the target system network.

The obtaining of the abnormal power amplification module is according to the related description of the above embodiment, which is not described herein. The target frequency band is a frequency band where the abnormal power amplification module supports the radio frequency signal of power amplification, and when the power amplification module 210 is in an abnormal state, it means that the target frequency band supported by the power amplification module 210 cannot work.

The network searching frequency band can be a frequency band of the radio frequency module for supporting radio frequency signal transmission in the target system network. The updating of the available network searching frequency band according to the target frequency band can be to remove the target frequency band from the original available network searching frequency band. The target standard network may be one or more standard networks, including, for example, GSM (Global System for Mobile Communications ), UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system), LTE (long term evolution ), NR (NewRadio, new air interface), etc., each of which may include multiple frequency bands. Taking an LTE network system and an NR network system as an example, the LTE signal and the NR signal include a low frequency signal, an intermediate frequency signal, a high frequency signal, and an ultrahigh frequency signal, respectively, and frequency division of the low frequency signal, the intermediate frequency signal, the high frequency signal, and the ultrahigh frequency signal may refer to the following table.

It should be noted that, in the 5G network, only the identifier before the sequence number is changed along the frequency band used by the 4G. In addition, the 5G network is further added with ultra-high frequency bands, such as N77, N78, N79, etc., which are not found in some 4G networks.

When the rf module is applied to the communication device, the communication device typically needs to search the network at the time of operation, and in the related art, the network searching process typically attempts to search all frequency bands supported by the rf module. When the power amplification module 210 is in an abnormal state, it means that the target frequency band implemented by the power amplification module 210 cannot work, and the search for the inoperable frequency band is continued, which may cause the equipment to crash. In this embodiment, the updated available network searching frequency band removes the target frequency band, and the device can skip the frequency band which cannot work when performing the operation of network searching, so that not only can the power consumption caused by network searching be reduced, but also the network searching time can be shortened, and the communication service speed can be accelerated.

Optionally, the power supply control circuit 30 may further comprise a control module, which may be, for example, an application processor (AP, application Processor) or a baseband processor in the communication device. The control module can acquire the target frequency band of the radio frequency signal supported by the abnormal power amplification module and update the available network searching frequency band according to the target frequency band. Optionally, the control module may further establish a network searching list according to the updated available network searching frequency band, so that the device may execute the network searching operation according to the network searching list. By establishing the network searching list, the network searching speed of the equipment can be further improved.

The above embodiments are further described below taking the example that at least two power modules include a first power module and a second power module, and at least two emission groups include a first emission group and a second emission group.

The first transmitting group comprises a low-frequency power amplifying module, a middle-high frequency amplifying module and a first ultrahigh frequency amplifying module which are respectively connected to the first power module and the second power module, wherein the low-frequency power amplifying module is used for supporting the power amplification of a low-frequency signal, the middle-high frequency amplifying module is used for supporting the power amplification of a middle-frequency signal and a high-frequency signal, the first ultrahigh frequency amplifying module is used for supporting the power amplification of an ultrahigh frequency signal, and each power amplifying module of the first transmitting group is connected with the first power module in a conducting mode by default; the second transmitting group comprises a high-frequency amplifying module and a second ultrahigh-frequency amplifying module which are respectively connected to the first power module and the second power module, the high-frequency amplifying module is used for supporting power amplification of high-frequency signals, the second ultrahigh-frequency amplifying module is used for supporting power amplification of ultrahigh-frequency signals, and each power amplifying module of the second transmitting group is connected with the second power module in a conducting mode by default.

The power supply control circuit 30 is configured to determine that the first power module is an abnormal power module and determine that the first emission group is an abnormal emission group when the first power module is in an abnormal operation mode and the operation mode of the second power module is different from the abnormal operation mode, identify an abnormal power amplification module from the first emission group, and control the normal power amplification module in the first emission group to be switched to be in conductive connection with the second power module; when the second power supply module is in an abnormal working mode and the working mode of the first power supply module is different from the abnormal working mode, determining that the second power supply module is an abnormal power supply module, determining that the second emission group is an abnormal emission group, identifying an abnormal power amplification module from the second emission group, and controlling the normal power amplification module in the second emission group to be switched to be connected with the first power supply module in a conducting mode.

As shown in fig. 5 (in the drawing, the power supply control circuit 30 includes a radio frequency transceiver and a control module, the radio frequency module further includes a switch module 40, the switch module 40 includes a plurality of switch units 410 for illustration, the low frequency power amplifying module, the middle high frequency amplifying module and the first ultrahigh frequency amplifying module in the first transmitting group are powered by the first power module by default, and the high frequency amplifying module and the second ultrahigh frequency amplifying module in the second transmitting group are powered by the second power module by default. The first power module is a power source 1, the second power module is a power source 2, the low-frequency amplifying module can be LB LPAMID modules, the medium-high frequency amplifying module can be MHB LPAMID modules, the first ultrahigh-frequency amplifying module can be an N78 LPAF#1 module, the high-frequency amplifying module can be an N41 LPAF PA module, the second ultrahigh-frequency amplifying module N78 LAPF #2 module, and the control module can be an AP. LB LPAMID module, MHB LPAMID module, N78 lpaf#1 module, N41 LPAF PA module, and N78 LAPF #2 module may each be connected to a corresponding antenna (e.g., ANT1, ANT2, ANT3, ANT4, and ANT5 in the figure) through a front end module, respectively.

Assuming that LB LPAMID is in PA burning short circuit, the radio frequency transceiver obtains the working mode of the first power supply module through the mipi interface for detection, and when the working mode is in an abnormal working mode, the first transmitting group is determined to be an abnormal transmitting group. The radio frequency transceiver sequentially sends a first control signal to each switch unit 410 corresponding to the first transmitting group through mipi or a GPIO interface for control, determines that the abnormal module is LB LPAMID, and the normal power amplification module is MHB LPAMID or n78lpaf#1, and then sends a second control signal to the switch units 410 corresponding to MHB LPAMID or n78lpaf#1 through mipi or a GPIO interface for control so as to switch to the second power module. The AP knows that the target frequency bands supported by LB LPAMID are low-frequency bands such as B5, B8, B28, n5, n8 and n28, and therefore the low-frequency bands such as B5, B8, B28, n5, n8 and n28 are removed from the network searching list.

It can be appreciated that the probability of PA burning short circuit is generally low, and the probability of abnormality occurring at the same time in the power amplification modules inside the first emission group and the second emission group is low, so that the power supply modules are generally switched between the first power supply module and the second power supply module. In order to avoid the situation that the power amplification modules in the first emission group and the second emission group have abnormality at the same time, a third power module can be added to perform switching candidate of the power modules.
