图1为一实施例的射频模组的结构框图，参考图1，在本实施例中，射频模组包括至少两个电源模块10、至少两个发射组20及供电控制电路30。
各发射组20包括至少两个功率放大模块210，各功率放大模块210可切换地导通连接至至少两个电源模块10中的任意一个，同一发射组20中的各功率放大模块210用于在同一的供电作用下对接收的射频信号进行功率放大(图1仅示出与各发射组20中功率放 大模块210导通连接的电源模块的连接情况，而未示出其他与功率放大模块210断开连接的电源模块10的连接情况)；供电控制电路30，用于获取各发射组20中各功率放大模块210的工作状态，根据工作状态确定异常功率放大模块所处的异常发射组，并控制异常发射组中正常功率放大模块由当前导通连接的电源模块10切换至目标电源模块，其中，目标电源模块为至少两个电源模块10中除当前导通连接的电源模块10之外的任意一个电源模块10。
其中，电源模块10的数量为至少两个，每个电源模块10可连接同一发射组20中的各功率放大模块210，也可连接不同发射组20的多个功率放大模块210，当电源模块10与功率放大模块210之间的连接导通时，电源模块10向导通连接的功率放大模块210提供供电信号，以使得功率放大模块210对接收的射频信号进行功率放大。可选地，电源模块10可以根据功率放大模块210需要支持功率放大的射频信号的频段进行电压调节，以输出适用于功率放大模块210正常工作的供电信号，以满足用户的需求。电源模块10例如可以包括电池和与电池连接的电源管理芯片(Power management IC，PMIC)，以将电池的电能进行调整后提供至功率放大模块210。
其中，发射组20的数量为至少两个，各发射组20包括至少两个功率放大模块210，从而射频模组包括多个功率放大模块210，多个功率放大模块210可以形成多个发射通路，从而射频模组支持多路发射处理，提高通信质量和用户体验。可选地，可以根据实际应用中各功率放大模块210接收的射频信号是否处于同一发射通路组对多个功率放大模块210进行分组，与同一发射通路组连接的多个功率放大模块210可以归属于同一发射组20。可选地，也可以根据需要支持功率放大的射频信号的频段进行分组，例如将低频频段、中频频段及高频频段的部分功率放大模块210划分在同一发射组20，将高频频段和超高频频段的部分功率放大模块210划分在同一发射组20，以支持不同频段组合；也可以根据各功率放大模块210的供电需求进行分组，例如将供电需求接近的不同功率放大模块210划分在同一发射组20。需要说明的是，本实施例并不局限于前述提及的分组方式，具体可以根据实际需求进行设定。
其中，各功率放大模块210切换连接至至少两个电源模块10，同一发射组20中的各功率放大模块210用于在同一电源模块的供电作用下对接收的射频信号进行功率放大。通常情况，在各发射组20都处于正常供电的情况下，不同发射组20中各功率放大模块210的导通连接的电源模块10默认不同。可以理解，切换连接是指功率放大模块210可分别连接至少两个电源模块10，并可以切换地导通功率放大模块210与一电源模块10之间的连接。
各功率放大模块210可以包括一个或多个功率放大器(Power amplifier，PA)，各PA的电源端切换连接至至少两个电源模块10，各PA的输入端用于与射频收发器连接以接收射频信号，各PA的输出端用于与天线或其他射频前端模块连接，当PA与电源模块之间的连接导通时，PA对接收的射频信号进行功率放大，并将功率放大后的射频信号输出至天线，以供天线向外发射。可选地，供电控制电路30可以包括射频收发器，当供电控制电路30包括射频收发器时，供电控制电路30可与各功率放大模块210的输入端连接，以向各功率放大模块210提供射频信号(图1以此为例，示出了供电控制电路30与各功率放大模块210的连接)。
可选地，功率放大模块210还可以包括其他功能器件以实现其他辅助功能，例如，还可以包括低噪声放大器以同时实现接收功能。当功率放大模块210还包括低噪声放大器时，功率放大模块210可以为内置低噪放的低频功率放大器模块(LB L-PA Mid，Low Band PA Mid With LNA)，还可以为内置低噪放的中高频功率放大器模块(MHB L-PA Mid，Middle and High Band PA Mid With LNA)，此外，还可以为集成有滤波器和低噪声放大器的功率放大器开关模组(LPAF，LNA-PA ASM module with integrated filter)等，例如，可 以是支持高频信号或者超高频信号的LPAF。

可选地，可以选定默认电源模块10作为当前导通连接的电源模块，在各功率放大模块210均处于正常工作状态时，开关模块40导通各功率放大模块210与默认电源模块10之间的连接通路，以使得各默认电源模块10对默认导通连接的发射组20进行供电；在存在异常功率放大模块时，开关模块40关断异常功率放大模块所处的发射组20中其他正常功率放大模块与该默认电源模块10之间的连接，同时导通正常功率放大模块与其他电源模块10之间的连接。
通过供电控制电路30和开关模块40可以在功率放大模块210出现异常时，及时对异常发射组中正常功率放大模块切换至目标电源模块，保证正常功率放大模块正常工作。
在一些实施例中，开关模块40还用于在供电控制电路30的控制下，断开异常功率放大模块与当前导通连接的电源模块的连接。
当功率放大模块210内部的PA烧毁后，异常功率放大模块与原先导通连接的电源模块之间的供电通路上会产生异常大电流，当供电控制电路30根据各功率放大模块210的工作状态判定出异常功率放大模块时，及时控制开关模块40断开异常功率放大模块与当前导通连接的电源模块的连接，可以避免功率放大模块210持续异常大电流，导致严重发热情况的出现。
在一些实施例中，如图2所示，供电控制电路30可以包括：射频收发器310和控制模块320。
控制模块320，用于获取各功率放大模块210的工作状态，在工作状态为异常工作状态时，生成电源切换指令，电源切换指令携带异常发射组及正常功率放大模块的参数信息；射频收发器310，分别与控制模块320、功率放大模块210的输入端、开关模块40的受控端连接，用于提供射频信号，还用于根据电源切换指令控制开关模块40将正常功率放大模块由当前导通连接的电源模块10切换至目标电源模块。
其中，控制模块320与射频收发器310连接，控制模块320能够获取各功率放大模块210的工作状态，并在工作状态为异常工作状态时，生成电源切换指令，以指示射频收发器310进行相应操作。控制模块320获取各功率放大模块210的工作状态的方式，可以参见上述实施例中的相关描述，在此不再赘述。可选地，当射频模组应用在通信设备中时，控制模块320可以是通信设备中的应用处理器(AP，Application Processor)或者基带处理器。以控制模块320为AP为例，则当AP根据各功率放大模块210的工作状态发现异常功率放大模块时，通过电源切换指令通知射频收发器310进行相应操作。
其中，射频收发器310分别与控制模块320、功率放大模块210的输入端、开关模块40的受控端连接，射频收发器310能够向功率放大模块210提供射频信号，还能够接收控制模块320输出的电源切换指令，由于电源切换指令携带异常发射组及正常功率放大模块的参数信息，因此射频收发器310可以根据各参数信息生成相应的控制信号，以控制开关模块40实现目标电源模块的切换。
通过控制模块320与射频收发器310之间的交互，可以及时发现异常功率放大模块，并及时控制开关模块40的导通情况，以使得开关模块40及时对异常发射组中正常功率放大模块切换目标电源模块，保证正常功率放大模块正常工作。
在一些实施例中，请继续参考图2，在本实施例中，开关模块40包括：多个开关单 元410，射频收发器310通过控制各开关单元410的导通情况实现对正常功率放大模块的目标电源模块的切换。

其中，开关单元410设置在各功率放大模块210与电源模块10之间的连接通路上，通过控制开关单元410的导通情况，即可控制电源模块10对各功率放大模块210的供电情况。控制信号包括导通信号和关断信号，导通信号用于控制开关单元410导通原先处于关断状态的连接通路，关断信号用于控制开关单元410关断原先处于导通状态的连接通路。
当射频收发器310接收到电源切换指令时，射频收发器310根据电源切换指令携带的参数信息确定需要进行目标电源模块切换的目标开关单元410，并生成控制信号以通过控制接口发送控制信号给相应的目标开关单元410，以控制目标开关单元410进行目标电源模块的切换。通过设置多个开关单元410，各开关单元410设置在各功率放大模块210与电源模块10的连接通路上，从而可以独立控制各开关单元410的导通和关断情况，更加精准地进行目标电源模块的切换。
可选地，射频收发器310的控制接口包括mipi(Mobile Industry Processor Interface，移动行业处理器接口)接口、GPIO(General Purpose Input Output，通用输入/输出)接口中的一种，射频收发器310可以通过mipi接口或GPIO接口的电平变化控制，向开关单元410发送控制信号，从而提高控制效率。
可选地，各开关单元410包括至少一个开关器件，开关器件例如可以是单刀多掷开关，例如，当功率放大模块210分别与两个电源模块10连接时，开关单元410可以是单刀双掷开关，单刀双掷开关的两个第一端分别与两个电源模块10的输出端对应连接，单刀双掷开关的第二端与功率放大模块210的电源端连接。可以配置单刀双掷开关默认导通其中一电源模块10与功率放大模块210之间的连接，断开另一电源模块10与功率放大模块210之间的连接；在供电控制电路30获取到异常功率放大模块时，单刀双掷开关断开正常功率放大模块与异常功率放大模块同时供电的电源模块10之间的连接，导通另外一电源模块10与正常功率放大模块之间的连接，以实现目标电源模块的切换。
在一些实施例中，开关单元410可以设置在功率放大模块210外部(图2的实施例以开关单元410外置为例进行示意，请辅助参考图2)。其中，各功率放大模块210可以被配置有电源接口及输入接口，电源接口与开关单元410的第二端连接，输入接口与射频收发器310的发射接口连接；其中，电源接口用于接收电源模块10的供电信号，输入接口用于接收射频收发器310输出的射频信号。
在一些实施例中，开关单元410可以集成在功率放大模块210中，如图3所示，各功率放大模块210包括功率放大器，各功率放大模块210被配置有至少两个电源接口、受控接口及输入接口(图3以两个电源接口为例进行示意，两个电源接口分别为VCC1和VCC2，输入接口为PAIN，受控接口为BC，图中未示出功率放大器和开关单元410)，至少两个电源接口分别与至少两个电源模块10对应连接，受控接口与射频收发器310的控制接口连接，输入接口分别与射频收发器310的发射接口、功率放大器的输入端连接；其中，各开关单元410集成在对应的功率放大模块210中，开关单元410的至少两个第一端分别与至少两个电源接口对应连接，开关单元410的第二端与功率放大器的电源端连接，开关单 元410的受控端与受控接口连接。
其中，功率放大模块210被配置有至少两个电源接口、受控接口及输入接口，各开关单元410集成在对应的功率放大模块210中，开关单元410的第一端通过电源接口与外部的电源模块10连接，开关单元410的第二端与功率放大模块210的功率放大器连接，开关单元410的受控端通过受控接口与外部的射频收发器310连接。通过将开关单元410集成在功率放大模块210内部，能够减少射频模组占用的主板面积，提高集成度，有利于射频模组的小型化，降低成本。
可以理解，当功率放大模块210包括多个功率放大器时，开关单元410也可以具有多个第二端，各第二端分别对应与一功率放大器的电源端连接。可以理解，功率放大模块210还被配置有输出接口，输出接口可以通过射频前端电路与天线连接。
在其他实施例中，开关单元410还可以集成在电源模块10中，例如可以将上述实施例中默认电源模块10对应的多个开关单元410集成在该默认电源模块10内部，以提高集成度，同样有利于射频模组的小型化，降低成本。
在一些实施例中，射频模组还可以包括：状态检测电路，供电控制电路30通过状态检测电路获取各功率放大模块210的工作状态。
状态检测电路，分别与控制模块320、功率放大模块210连接，用于检测功率放大模块210的工作状态，将工作状态反馈至控制模块320。具体地，状态检测电路可以检测功率放大模块210的状态参数，根据状态参数确定功率放大模块210的工作状态，将工作状态反馈至控制模块320，以供控制模块320获取。
可选地，状态检测电路可以根据状态检测结果，生成具有状态标志位变化的信号，例如，在检测到有异常功率放大模块时，产生一个拉高或者拉低电平信号，该拉高或者拉低电平信号用于向控制模块320指示对应功率放大模块210处于异常工作状态。可选地，状态检测电路可以是电压检测电路、电流采样电路、温度检测电路等，用于通过功率放大模块210的状态参数检测功率放大模块210的工作状态。可以理解，当状态检测电路为电压检测电路、电流采样电路时，状态检测电路可与功率放大模块210连接，当状态检测电路为温度检测电路时，状态检测电路也可以不与功率放大模块210连接，通过检测功率放大模块210周围环境的温度获取温度参数。
可选地，状态检测电路的数量可以为一个，该状态检测电路可以具有多个检测端和多个反馈端，各检测端可以与各个功率放大模块210连接，各反馈端与控制模块320各反馈接收端连接，状态检测电路用于将各检测端检测获得工作状态在对应的反馈端反馈，以使得控制模块320通过反馈接收端接收的状态信号即可确定各个功率放大模块210的工作状态。
可选地，状态检测电路的数量可以为多个，如图4所示，各功率放大模块210还被配置有状态反馈接口(状态反馈接口如图中的BD)；其中，各状态检测电路对应集成在各功率放大模块210中，各状态检测电路的反馈端通过状态反馈接口与控制模块320的检测接口连接，各状态检测电路的检测端与功率放大器的电源端连接(图中未示出功率放大器及状态检测电路)。
通过将各状态检测电路集成在功率放大模块210内部，一方面能够减少射频模组占用的主板面积，提高集成度，有利于射频模组的小型化，降低成本；另一方面，可以缩短状态检测电路与功率放大器电源端之间的检测距离，提高状态检测电路的检测精度。
在一些实施例中，供电控制电路30，还用于获取异常功率放大模块支持功率放大的射频信号的目标频段，根据目标频段更新可用搜网频段，可用搜网频段为射频模组在目标制式网络中支持射频信号发射的频段。
其中，目标频段为异常功率放大模块支持功率放大的射频信号所处的频段，在功率放大模块210处于异常状态时，意味着该功率放大模块210支持的目标频段已无法工作。
其中，可用搜网频段为射频模组在目标制式网络中支持射频信号发射的频段。根据目标频段更新可用搜网频段，可以是在原可用搜网频段中去除目标频段。目标制式网络可以是一种或多种制式网络，例如包括GSM(Global System for Mobile Communications，全球移动通信系统)、UMTS(Universal Mobile Telecommunications System，通用移动通信系统)、LTE(长期演进，Long Term Evolution)和NR(NewRadio，新空口)等，每种网络制式可用包括多个频段。本实施例不做进一步限定。以LTE网络制式和NR网络制式为例，LTE信号和NR信号分别包括低频信号、中频信号、高频信号和超高频信号，其中低频信号、中频信号、高频信号和超高频信号的频段划分可以参照下表。
需要说明的是，5G网络中沿用4G所使用的频段，仅更改序号之前的标识。此外，5G网络还新增了一些4G网络中没有的超高频段，例如，N77、N78和N79等。
当射频模组应用在通信设备中时，通信设备在运行时通常需要搜索网络，在相关技术中，网络搜索过程通常是对射频模组支持的所有频段均尝试搜索。而在功率放大模块210处于异常状态时，意味着该功率放大模块210实现的目标频段已无法工作，继续对无法工作的频段进行搜索，可能导致设备出现死机风险。在本实施例中，更新的可用搜网频段去除了目标频段，可供设备在执行网络搜索的操作时跳过无法工作的频段，从而不仅能够降低由于网络搜索所带来的功耗，而且还能够缩短网络搜索时间，加快通信服务速度。
可选地，可以由供电控制电路30中的控制模块320获取异常功率放大模块支持功率放大的射频信号的目标频段，并根据目标频段更新可用搜网频段。可选地，控制模块320还可以根据更新后的可用搜网频段建立搜网列表，以供设备根据搜网列表执行网络搜网的操作。通过搜网列表的建立，能够进一步提高设备的搜网速度。
以下以至少两个电源模块包括第一电源模块和第二电源模块，至少两个发射组包括第一发射组和第二发射组为例对上述实施例进行进一步说明：
第一发射组，包括分别连接至第一电源模块和第二电源模块的低频功率放大模块、中高频放大模块及第一超高频放大模块，低频功率放大模块用于支持对低频信号的功率放大，中高频放大模块用于支持对中频信号和高频信号的功率放大，第一超高频放大模块用于支持对超高频信号的功率放大，第一发射组中各功率放大模块默认与第一电源模块导通连接；第二发射组，包括分别连接至第一电源模块和第二电源模块的高频放大模块及第二超高频放大模块，高频放大模块用于支持对高频信号的功率放大，第二超高频放大模块用于支持对超高频信号的功率放大，第二发射组中各功率放大模块默认与第二电源模块导通连接。
其中，供电控制电路30，用于在第一发射组包括至少一个异常功率放大模块且第二发射组未包括异常功率放大模块时，将第一发射组中正常功率放大模块由当前导通连接的第一电源模块切换至第二电源模块，或者在第二发射组包括至少一个异常功率放大模块且第一发射组未包括异常功率放大模块时，将第二发射组中正常功率放大模块由当前导通连接的第二电源模块切换至第一电源模块。
如图5所示(图中以供电控制电路30包括射频收发器310和控制模块320，射频模组还包括状态检测电路及开关模块40，开关模块40包括多个开关单元410为例进行示意)， 第一发射组中低频功率放大模块、中高频放大模块及第一超高频放大模块默认由第一电源模块供电，第二发射组中高频放大模块及第二超高频放大模块默认由第二电源模块供电。其中，第一电源模块为电源1，第二电源模块10为电源2，低频放大模块可以为LB LPAMID模块，中高频放大模块可以为MHB LPAMID模块，第一超高频放大模块可以为N78 LPAF#1模块，高频放大模块可以为N41 LPAF PA模块，第二超高频放大模块N78 LAPF#2模块，控制模块320可以为AP。LB LPAMID模块、MHB LPAMID模块、N78 LPAF#1模块、N41 LPAF PA模块及N78 LAPF#2模块各自分别可以通过前端模块与对应的天线(如图中的ANT1、ANT2、ANT3、ANT4及ANT5)连接。
假设LB LPAMID模块发生PA烧片短路，AP通过状态检测电路获取LB LPAMID模块处于异常工作状态，确定第一发射组为异常发射组，继而生成电源切换指令通知射频收发器310，射频收发器310根据电源切换指令生成控制信号，并通过mipi或者GPIO接口发送控制信号至MHB LPAMID模块及N78 LPAF#1模块对应的开关单元410，以控制开关单元410将当前导通连接的第一电源模块切换至第二电源模块。同时，AP可以将B5、B8、B28、n5、n8、n28等低频频段从搜网列表中去除。
假设N78 LAPF#2模块发生PA烧片短路，AP通过状态检测电路获取N78 LAPF#2模块处于异常工作状态，确定第二发射组为异常发射组，继而生成电源切换指令通知射频收发器310，射频收发器310根据电源切换指令生成控制信号，并通过mipi或者GPIO接口发送控制信号至N41 LPAF模块对应的开关单元410，以控制开关单元410将当前导通连接的第二电源模块切换至第一电源模块。同时，AP可以将N78超高频频段从搜网列表中去除。
可以理解，通常PA烧片短路的概率比较低，第一发射组和第二发射组内部的功率放大模块同时发生异常的概率很低，因此，目标电源模块通常在第一电源模块和第二电源模块中切换即可。为了避免极小概率的第一发射组和第二发射组内部的功率放大模块同时发生异常的情况，也可以增加第三电源模块，以进行目标电源模块的切换备选。
上述射频模组中各个模块、电路的划分仅仅用于举例说明，在其他实施例中，可将射频模组按照需要划分为不同的电路，以完成上述射频模组的全部或部分功能。
