具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
可以理解，本申请所使用的术语“第一”、“第二”等可在本文中用于描述各种元件，但这些元件不受这些术语限制。这些术语仅用于将第一个元件与另一个元件区分。举例来说，在不脱离本申请的范围的情况下，可以将第一输入端口称为第二输入端口，且类似地，可将第二输入端口称为第一输入端口。第一输入端口和第二输入端口两者都是输入端口，但其不是同一输入端口。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。在本申请的描述中，“若干”的含义是至少一个，例如一个，两个等，除非另有明确具体的限定。
本申请实施例涉及的射频PA Mid器件可以用于构建射频系统，射频系统可以应用到具有无线通信功能的通信设备，其通信设备可以为手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)(例如，手机)，移动台(Mobile Station，MS)等等。为方便描述，上面提到的设备统称为通信设备。
图1为一实施例的射频PA Mid器件10的结构示意图之一，参考图1，在其中一个实施例中，射频PA Mid器件10被配置有用于连接射频收发器的第一输入端口和第二输入端口，以及用于连接天线的第一中高频天线端口ANT3。其中，第一输入端口和第二输入端口分别用于传输不同制式的信号，以使射频PA Mid器件10能够实现对第一制式和第二制式的信号的发射处理，所述第二制式与所述第一制式不同。射频信号可包括2G制式、4G制式和5G制式的低、中、高频信号。其中，天线可以使用任何合适类型的天线形成，例如，可以包括由以下天线结构形成的具有谐振元件的天线：阵列天线结构、环形天线结构、贴片天线结构、缝隙天线结构、螺旋形天线结构、带状天线、单极天线、偶极天线中的至少一种。其中，不同类型的天线可以用于不同的频段和频段组合。
在本申请各实施例中，以第一输入端口用于传输4G制式和5G制式的中高频信号，第二输入端口用于传输2G制式的高频信号为例进行说明。相应地，第一输入端口可称为4G RFIN，第二输入端口可称为2G HB IN。需要说明的是，虽然图1中部分端口以4G制式进行命名，但是上述端口可以用于传输5G制式的信号。进一步地，为了提高射频PA Mid器件10对4G制式信号的中高频信号的处理性能，本申请实施例的射频PA Mid器件10将4G制式的中频信号和高频信号分别进行处理。中高频信号可以包括4G LTE信号、5G NR信号中的中频信号和高频信号。其中，中频信号可包括至少一个中频频段的射频信号，例如包括B1、B3、B66、B25、B34、B39等频段的射频信号。高频信号可包括至少一个高频频段的射频信号，例如包括B7、B40、B41等频段的射频信号。相应地，射频PA Mid器件10可以被配置有两个第一输入端口，分别称为4G MB RFIN和4G HB RFIN，以分别传输不同频段范围的信号。
所述射频PA Mid器件10包括第一发射模块110、第二发射模块120和第一开关模块210。第一发射模块110与所述第一输入端口4G MB RFIN和4G HB RFIN连接，用于支持对来自所述第一输入端口4G MB RFIN和4G HB RFIN的第一制式的中高频信号的发射处理。第二发射模块120与所述第二输入端口2G HB IN连接，用于支持对来自所述第二输入端口2G HB IN的第二制式的高频信号的发射处理。其中，各发射模块分别包括至少一个功率放大器(Power Amplifier，PA)，并可以进一步包括滤波器、合路器、双工器、开关等器件中的至少一个，以支持更加复杂的发射处理功能。所述第一开关模块210包括多个第一端和多个第二端，第一开关模块210的部分第一端分别与所述第一发射模块110、所述第二发射模块120连接，所述第一开关模块210的一个第二端与所述第一中高频天线端口ANT3连接，所述第一开关模块210用于选择导通任一第一端与连接所述第一中高频天线端口ANT3的第二端之间的信号传输通路。
进一步地，第一发射模块110可以将发射处理后的不同频段的信号分别经不同的端口输出至第一开关模块210，以分别对不同频段的中高频信号进行发射。因此，第一发射模块110与第一开关模块210之间可以形成有多个信号传输通路，每个信号传输通路用于传输不同频段的信号，从而扩展射频PA Mid器件10能够处理的频段范围。而且，在每个信号传输通路上，可以分别设置对应频段的滤波器，从而对信号传输通路传输的信号进行滤波处理，提高信号传输质量。例如，在图1所示的实施例中，第一发射模块110与第一开关模块210之间有两个信号传输通路，则可以在每个信号传输通路上分别设置一个对应的第二中高频滤波器，且仅允许与所在的信号传输通路需要传输频段的信号通过，并隔离需要传输频段以外的其他信号，从而分别对不同频段的信号进行滤波处理。
在本实施例中，射频PA Mid器件10包括两个中高频的发射模块，以支持对不同制式的中高频信号的发射处理。由于第一发射模块110和第二发射模块120处理的信号均为中高频信号，集成设置的时候也具有较好的兼容性。而且，由于不同制式的中高频信号通常不需要同时发射，因此，通过设置第一开关模块210，可以将不同制式的中高频信号经同一第一中高频天线端口ANT3分时进行发射，从而减少需要设置的天线端口的数量，提高射频PA Mid器件10的集成度。
图2为一实施例的射频PA Mid器件10的结构示意图之二，参考图2，在其中一个实施例中，射频PA Mid器件10还被配置有用于连接射频收发器的第一输出端口LNA OUT，第一输出端口LNA OUT用于将接收处理后的中高频信号传输至射频收发器。所述射频PA Mid器件10还包括第一接收模块310。第一接收模块310与所述第一输出端口LNA OUT连接，用于支持对来自所述第一中高频天线端口ANT3的所述第一制式的中高频信号的接收处理，并将处理后的信号传输至所述第一输出端口LNA OUT。其中，所述第一开关模块210的部分第一端与所述第一接收模块310连接，所述第一开关模块210还用于选择传输来自所述第一中高频天线端口ANT3的所述第一制式的中高频信号至所述第一接收模块310。即，在进行信号发射时，第一开关模块210可以选择将第一发射模块110或第二发射模块120导通至第一中高频天线端口ANT3，以实现对中高频信号的发射；在进行信号接收时，第一开关模块210可以选择将第一中高频天线端口ANT3导通至第一接收模块310，以实现对中高频信号的接收。
在本实施例中，通过集成第一接收模块310，可以对第一制式的中高频信号进行接收处理，从而无需设置外置的接收模块的前提下，对第一制式的中高频信号进行接收，进而减少外置的走线数量，提高射频系统的集成度。可以理解的是，与第一发射模块110相似地，第一接收模块310也可以设置多个用于连接第一开关模块210的端口，从而在第一接收模块310与第一开关模块210之间形成多个信号传输通路，以分别经不同的信号传输通路传输不同频段的信号。而且，第一接收模块310与第一开关模块210之间的信号传输通路上也可以设置滤波器，以提高发射的中高频信号的信噪比。
图3为一实施例的射频PA Mid器件10的结构示意图之三，参考图3，在其中一个实施例中，射频PA Mid器件10还被配置有用于连接所述射频收发器的第三输入端口4G LB RFIN和第四输入端口2G LB RFIN，以及用于连接天线的第一低频天线端口ANT1。其中，第一制式的低频信号可以包括4G LTE信号、5G NR信号中的任一低频频段的射频信号，示例性地，可包括B8、B12、B20、B26、B28A等频段中多个频段的射频信号。
所述射频PA Mid器件10还包括第三发射模块130、第四发射模块140和第二开关模块220。第三发射模块130与所述第三输入端口4G LB RFIN连接，用于支持对来自所述第三输入端口4G LB RFIN的第一制式的低频信号的发射处理。第四发射模块140与所述第四输入端口2G LB RFIN连接，用于支持对来自所述第四输入端口2G LB RFIN的第二制式的低频信号的发射处理。所述第二开关模块220包括多个第一端和多个第二端，第二开关模块220的部分第一端分别与所述第四发射模块140、所述第三发射模块130一一对应连接，所述第二开关模块220的一个第二端与所述第一低频天线端口ANT1连接，所述第二开关模块220用于选择导通任一第一端与连接所述第一低频天线端口ANT1的第二端之间的信号传输通路。即，第二开关模块220可以选择将第三发射模块130导通至第一低频天线端口ANT1，以实现对第一制式的低频信号的发射，也可以选择将第四发射模块140导通至第一低频天线端口ANT1，以实现对第二制式的低频信号的发射。
在本实施例中，射频PA Mid器件10还包括两个低频的发射模块，以支持对不同制式的低频信号的发射处理，从而使射频PA Mid器件10能够分别对低频和中高频的信号进行收发。而且，通过设置第二开关模块220，可以将不同制式的低频信号经同一第一低频天线端口ANT1分时进行发射，从而减少需要设置的天线端口的数量，提高射频PA Mid器件10的集成度。
图4为一实施例的射频PA Mid器件10的结构示意图之四，参考图4，在其中一个实施例中，射频PA Mid器件10还被配置有用于连接所述射频收发器的第二输出端口LNA OUT，第二输出端口LNA OUT用于将接收处理后的低频信号传输至射频收发器。所述射频PA Mid器件10还包括第二接收模块320。第二接收模块320与所述第二输出端口LNA OUT连接，用于支持对来自所述第一低频天线端口ANT1的 所述第一制式的低频信号的接收处理，并将处理后的信号传输至所述第二输出端口LNA OUT。其中，所述第二开关模块220的部分第一端与所述第二接收模块320连接，所述第二开关模块220还用于选择传输来自所述第一低频天线端口ANT1的所述第一制式的低频信号至所述第二接收模块320。即，在进行信号发射时，第二开关模块220可以选择将第三发射模块130或第四发射模块140导通至第一低频天线端口ANT1，以实现对低频频信号的发射；在进行信号接收时，第二开关模块220可以选择将第一低频天线端口ANT1导通至第二接收模块320，以实现对低频信号的接收。
图5为一实施例的射频PA Mid器件10的结构示意图之五，参考图5，在其中一个实施例中，射频PA Mid器件10还被配置有用于连接射频LFEM器件的第一收发端口TRX。其中，所述第一开关模块210的一个第一端与所述第一收发端口TRX连接。可以理解的是，在封装射频PA Mid器件10后，其内部的信号传输通路是固定不变的，而无法实现更加复杂的信号收发功能。但在本实施例中，通过设置第一收发端口TRX，可以将第一中高频天线端口ANT3接收到的中高频信号传输至射频LFEM器件进行接收处理，以拓展射频系统的收发功能，从而可以对更多频段的射频信号进行主分集接收和MIMO接收等。例如，若射频PA Mid器件10仅包括一个连接至第一低频天线端口ANT1的B41频段的接收通路，则可以控制第一中高频天线端口ANT3也同时接收B41频段的信号，并将接收到的信号经第一收发端口TRX输出至射频LFEM器件，以实现对B41频段的信号的双路接收。
图6为一实施例的射频PA Mid器件10的结构示意图之六，本实施例细化了每个发射模块和接收模块内部的具体结构。参考图6，第一发射模块110包括中频信号发射单元和高频信号发射单元，中频信号发射单元与第一输入端口4G MB RFIN连接，高频信号发射单元与第一输入端口4G HB RFIN连接。中频信号发射单元包括至少一个中频4G功率放大器，以及与中频4G功率放大器连接的射频开关，以将不同频段的信号经不同的信号传输通路进行输出。高频信号发射单元包括多个中高频4G功率放大器，以及与中高频4G功率放大器连接的射频开关，以将不同频段的信号传输至不同的中高频4G功率放大器，并经不同的信号传输通路进行输出。第二发射模块120包括至少一个高频2G功率放大器。
