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发射端口RFIN1、第二发射端口RFIN2，及多个用于连接天线Ant的天线轮射端口SRS。天线轮射端口SRS可以理解为配置在该射频PA Mid器件10中与天线组20内各天线Ant连接的各射频引脚。其中，天线轮射端口SRS的数量与天线Ant的数量相等，且一个天线轮射端口SRS对应与一个天线Ant连接。第一发射端口RFIN1、第二发射端口RFIN2可以理解为配置在射频PA Mid器件10用于与射频收发器连接的射频端子。
其中，第一收发电路110，与第一发射端口RFIN1连接，用于经第一发射端口RFIN1接收第一射频信号，并对接收的第一射频信号进行放大滤波处理；第二收发电路120，与第二发射端口RFIN2连接，用于经第二发射端口RFIN2接收第二射频信号，并对接收的第二射频信号进行放大滤波处理。

在其中一个实施例中，第一开关单元114、第二开关单元124可以为单刀双掷(SPDT)开关，还可以为电子开关管、移动产业处理器(Mobile Industry Processor Interface，MIPI)接口和/或通用输入/输出(General-purpose input/output，GPIO)接口等。当第一开关单元114、第二开关单元124为MIPI接口或GPIO接口时，可以通过MIPI控制单元和/或GPIO控制单元对第一开关单元114、第二开关单元124的导通或断开状态进行控制。需要说明的是，在本申请实施例中，对第一开关单元114、第二开关单元124的具体形式不做进一步的限定。
在其中一个实施例中，当射频PA Mid器件10包括第一开关单元114和第二开关单元124，且天线轮射端口SRS的数量为四个(可分别记为SRS1、SRS2、SRS3、SRS4)时，多通道选择开关130包括两个第一端(可分别记为P1、P2)和四个第一端(可分别记为T1、T2、T3、T4)。示例性的，多通道 选择开关130可为射频DP4T开关。其中，射频DP4T开关的一第一端P1与第一滤波器112连接，另一第一端P2与第二滤波器122连接，一第二端T1与天线轮射端口SRS1连接，另一一第二端T2与天线轮射端口SRS2连接，又一第二端T3与天线轮射端口SRS3连接，再一第二端T4与天线轮射端口SRS4连接。也即，当多通道选择开关130的一第一端P1与第一滤波器112连接时，可经过射频DP4T开关的切换控制，使第一射频信号从天线轮射端口SRS1至SRS4中的任意一个端口输出，当多通道选择开关130的另一第一端P2与第二滤波器122连接时，可经过射频DP4T开关的切换控制，使第一射频信号从天线轮射端口SRS1至SRS4中的任意一个端口输出。
以图3所示的射频PA Mid器件10，对第一射频信号(N77频段的5G信号)的轮发和接收控制为例进行工作机理说明：
第一射频信号从第一发射端口RFIN1进入，经第一功率放大器111传输至第一开关单元114，由第一开关单元114切换至第一滤波器112后，到达多通道选择开关130的第一端，经多通道选择开关130的切换，第一射频信号可以从四个天线轮射端口(SRS1至SRS4中)中的任意一个端口输出以支持第一射频信号的SRS轮发功能。相应的，天线Ant接收的第一射频信号可经天线轮射端口(SRS1至SRS4中)中的任意一个端口输入，再由多通道选择开关130切换至第一收发电路110中的接收通道，经第一滤波器112至第一开关单元114，再由第一开关单元114切换第一低噪声放大器113，由第一低噪声放大器113经第一接收端口RX1输出至射频收发器。
在本实施例中，第一收发电路110能够实现对第一射频信号的收发控制，同时也能够支持第一射频信号在多个天线Ant之间的轮发，以实现SRS功能；相应的，第二收发电路120能够实现对第二射频信号的收发控制，同时也能够支持第二射频信号在多个天线Ant之间的轮发，以实现SRS功能。也即，该射频PA Mid器件10能够支持对N77和N79双频段信号的收发控制，还能够支持双频段探测参考信号经多个天线轮射端口SRS在多个天线Ant间轮发的功能。相比于传统射频PA Mid器件10，减少了发射通路上的开关数量(例如，传统射频PA Mid器件10中至少要设置两个射频开关器件，例如级联的DP3T开关、3P4T开关)，可以降低发射通路的插损，同时也降低了射频PA Mid器件10的占用空间，降低了成本，还提升了射频系统的通信性能。
如图4所示，在其中一个实施例中，在如图2所示的射频PA Mid器件10的基础上，射频PA Mid器件10还被配置有用于连接射频收发器的第一接收端口RX1、第二接收端口RX2。第一收发电路110还包括第三低噪声放大器115和第三滤波器116。其中，第三低噪声放大器115的输出端与第一接收端口RX1连接，用于对接收的第一射频信号进行放大处理；第三滤波器116分别与第三低噪声放大器115的输入端、多通道选择开关130的第一端连接，用于对接收的第一射频信号进行滤波处理。也即，基于第三低噪声放大器115和第三滤波器116以实现对第一射频信号的接收控制。第二收发电路120还包括第四低噪声放大器125和第四滤波器126。其中，第四低噪声放大器125的输出端与第一接收端口RX1连接，用于对接收的第二射频信号进行放大处理；第四滤波器126，分别与第四低噪声放大器125的输入端、多通道选择开关130的第一端连接，用于对接收的第二射频信号进行滤波处理。也即，基于第四低噪声放大器125和第四滤波器126可以实现对第二射频信号的接收控制。
在其中一个实施例中，当射频PA Mid器件10包括第三滤波器116和第四滤波器126，且天线轮射端口SRS的数量为四个(可分别记为SRS1、SRS2、SRS3、SRS4)时，多通道选择开关130包括四个第一端(可分别记为P1、P2、P3、P4)和四个第二端(可分别记为T1、T2、T3、T4)。在其中一个实施例中，多通道选择开关130为射频4P4T开关。也即，射频4P4T开关的任一第一端P1、P2、P3或P4均可与四个第二端(T1、T2、T3、T4)连接。其中，射频4P4T开关的一第一端P1与第一滤波器112连接，另一第一端P2与第二滤波器122连接，又一第一端P3与第三滤波器116连接，再一第一端P4与第四滤波器126连接；一第二端T1与天线轮射端口SRS1连接，另一第二端T2与天线轮射端口SRS2连接，又一第二端T3与天线轮射端口SRS3连接，再一第二端T4与天线轮射端口SRS4连接。也即，当多通道选择开关130的第一端P1与第一滤波器112连接时，可经过射频DP4T开关的切换控制，使第一射频信号从天线轮射端口SRS1至SRS4中的任意一个端口输出，当多通道选择开关130的第一端P2与第二滤波器122连接时，可经过射频DP4T开关的切换控制，使第一射频信号从天线轮射 端口SRS1至SRS4中的任意一个端口输出。
以图4所示的射频PA Mid器件10，对第一射频信号(N77频段的5G信号)的轮发和接收控制为例进行工作机理说明：
第一射频信号从第一发射端口RFIN1进入，经第一功率放大器111、第一滤波器112后，到达多通道选择开关130的第一端，经多通道选择开关130的切换，第一射频信号可以从四个天线轮射端口(SRS1至SRS4中)中的任意一个端口输出以支持第一射频信号的SRS轮发功能。相应的，天线Ant接收的第一射频信号可经天线轮射端口(SRS1至SRS4中)中的任意一个端口输入，再由多通道选择开关130切换至第一收发电路110中的接收通道，经第三滤波器116、第一低噪声放大器113、第一接收端口RX1输出至射频收发器。
如图3所示的射频PA Mid器件10中，器件内部的收发通道上设有多通道选择开关130(例如，射频DP4T开关)、第一开关单元114(例如，SPDT开关)和第二开关单元124(例如，SPDT开关)，共计三个切换开关。以普遍使用的射频DP4T开关为QM11024为例，其多通道选择开关130的插入损耗如表1所示，其射频PA Mid器件10中各频段的射频，如表2所示。

插入损耗(dB) 0.7 0.9
表2链路射频线损耗值
频段(GHz) N77 N79
插入损耗(dB) 2.9 2.8
如图4所示的射频PA Mid器件10中，省去了用于收发通道切换的第一开关单元114和第二开关单元124，可降低射频PA Mid器件10收发通道的链路损耗的。示例性的，第一开关单元114、第二开关单元124为SPDT开关(例如，RF1630)为例，其第一开关单元114或第二开关单元124插入损耗如表3所示。

表4 N77、N79通道天线轮射端口SRS输出功率
频段(GHz) N77 N79
天线Ant口功率(dB) 25.55 25.45
以第一发射端口RFIN1的输出功率为28.5dBm为例进行说明。天线轮射端口SRS的输出功率为28.5-2.9-0.7+0.65＝25.55dBm，N77、N79的天线轮射端口SRS输出功率如表4所示。从表4可以看出，N77通道天线轮射端口SRS输出功率为25.55dBm，符合研发的设计要求。
如图5所示，在其中一个实施例中，射频PA Mid器件10被配置有耦合输出端口CPLOUT，射频PA Mid器件10还包括第一耦合单元141、第二耦合单元142和耦合开关单元143。
第一耦合单元141，设置在第一收发电路110的发射通路中，用于耦合第一射频信号，以输出第一耦合信号，其中，第一耦合信号包括第一前向耦合信号和第一反向耦合信号。第二耦合单元142，设置在第二收发电路120的发射通路中，用于耦合第二射频信号，以输出第二耦合信号，其中，第二耦合信号包括第二前向耦合信号和第二反向耦合信号。
第一耦合单元141包括输入端a、输出端b、第一耦合端c和第二耦合端d。同时，第一耦合单元141还包括在输入端a和输出端b之间延伸的主线、以及在第一耦合端c和第二耦合端d之间延伸的副线。其中，第一耦合单元141的输入端a与第一功率放大器111的输出端连接，第一耦合单元141的输出端b与第一开关单元114连接，第一耦合端c用于对输入端a接收的射频信号进行耦合并输出第一前向耦合信号；第二耦合端d用于对第一射频信号的反射信号进行耦合并输出第一反向耦合信号。其中，基于第一耦合端c输出的第一前向耦合信号，可以检测该第一射频信号的前向功率信息，并将该检测模式定义为前向功率检测模式。基于第二耦合端d输出的第一反向耦合信号，可以对应检测该第一射频信 号的反向功率信息，并将该检测模式定义为反向功率检测模式。
相应的，基于第二耦合单元142的第一耦合端和第二耦合端也可以实现对第二射频信号的前向功率检测和反向功率检测。其中，第二耦合单元142与第一耦合单元141结构、工作原理相同，在此，对第二耦合单元142的结构、工作原理不再赘述。
耦合开关单元143，分别与第一耦合单元141、第二耦合单元142连接，用于选择将第一前向耦合信号、第一反向耦合信号、第二前向耦合信号或第二反向耦合信号经耦合输出端口CPLOUT输出，也即用于选择切换第一耦合单元141和第二耦合单元142，以输出第一耦合信号或第二耦合信号，进而实现检测第一耦合信号和第二耦合信号的功率信息。其中，功率信息包括向前功率和反向功率。
在其中一个实施例中，耦合开关单元143包括四个第一触点(1，2，3，4)和两个第二触点(5，6)。其中，一第一触(1)与第一耦合单元141的第二耦合端连接，一第一触点(2)与第一耦合单元141的第一耦合端连接，一第一触点(4)与第二耦合单元142的第一耦合端连接，一第一触点(3)与第二耦合单元142的第二耦合端连接；一第二触点(6)与耦合输出端口CPLOUT连接，一第二触点(5)接地。
示例性的，以采集第一射频信号的功率信息、耦合开关单元143为射频DP4T开关为例进行说明。
当需要采集第一耦合单元141的第一反向耦合信号时，射频DP4T开关的触点(5)连接到触点(1)，将泄露的第一前向耦合信号经负载接地，避免对第二耦合端(反向功率输出端口)造成干扰，射频DP4T开关的触点(6)连接到触点(2)，将第一反向耦合信号导出到耦合输出端口CPLOUT。采样第一耦合单元141的第一前向耦合信号时，射频DP4T开关的触点(5)连接到触点(2)，触点(6)连到触点(1)，将泄露的第一反向耦合信号经负载接地，避免对第二耦合端(反向功率输出端口)造成干扰。
需要说明的是，采集第二射频信号的功率信息的控制过程与采集第一射频信号的功率信息的控制过程类似，在此不再赘述。
在本申请实施例中，仅设置一个耦合开关单元143(例如射频DP4T开关)，就可以实现第一耦合单元141和第二耦合单元142的切换，减小占用封装的面积，同时也降低了成本。由于第一耦合单元141和第二耦合单元142不会同时工作，仅设置一个耦合输出端口CPLOUT，就可以满足需求；减少器件内部的射频走线复杂度，同时也可以提高内部各走线的隔离度性能。
在其中一个实施例中，射频PA Mid器件10还包括电阻R，一第二触点5经电阻R接地。具体的，该电阻R的阻值可以设为50欧姆，使泄露的前向耦合信号或者反向耦合信号接地，解决了第一耦合单元141或第二耦合单元142反向耦合信号输出时，正向耦合信号对于反向输出端口的干扰。
如图6所示，在其中一个实施例中，基于如图5所示的射频PA Mid器件10，射频PA Mid器件10还被配置有耦合输入端口CPLIN。当射频PA Mid器件10中配置了该耦合输入端口CPLIN时，其多通道选择开关130第一触点的数量也需要对应增加一个。示例性的，该多通道选择开关130可以为DP5T开关。也即耦合开关单元143包括五个第一触点(1，2，3，4，5)和两个第二触点(6，7)。其中，一第一触点(5)与耦合输入端口CPLIN连接。一第二触点(7)与耦合输出端口CPLOUT连接，一第二触点(触点6)接地。
在本实施例中，可将射频DP4T开关替换成DP5T开关，第一触点的数量增加到5个，当第二触点(7)与第一触点(5)连接时，可形成一个通路，外部耦合信号(前向耦合信号或反向耦合信号)可以从耦合输入端口CPLIN进入，再由耦合输出端口CPLOUT输出。耦合输入端口CPLIN可以接收其他射频PA Mid器件10的耦合输出端口CPLOUT输出的耦合信号，进而可以缩短用于传输耦合信号的射频走线长度，减小了射频系统布局的复杂度，同时还减少射频系统占用PCB的面积，降低了成本。

随着技术的发展和进步，5G移动通信技术逐渐开始应用于通信设备。5G网络支持波束赋形技术，可以向通信设备定向发射。而基站要想定向发射，首先得探测到通信设备的位置、传输通路的质量等，从而使基站的资源更加精准地分配给每一个通信设备。
目前，通信设备反馈信道信息有预编码矩阵指示符(Precoding Matrix Indicator，PMI)和信道探测参考信号(Sounding Reference Signal，SRS)这两种不同的模式，信号传输分别图13a和13b所示。从标准定义上看，PMI是所有5G通信设备必须支持的功能，SRS则是可选功能。PMI是基站通过一种预先设定的机制，依靠终端测量后辅以各种量化算法，来估计信道信息和资源要求，并上报给基站；而SRS则是利用信道互易性让终端直接将信道信息上报给基站，显然后者更加精确。
通信设备发送SRS信息即是用于基站探测终端位置和信道质量的方式；其中SRS天线Ant轮发如图13所示，具体说明如下：
其一，1T1R：固定在第一天线Ant0向基站反馈信息，不支持SRS轮发；
其一，1T4R：在第一天线Ant0到第四天线Ant3轮流发射SRS信息，每次只选择一个天线发射，目前非独立组网(Non-standalone，NSA)采用这种模式；
其三，2T4R：在第一天线Ant0到第四天线Ant3轮流发射SRS信息，每次选择两个天线同时发射，目前独立组网(Standalone，SA)采用这种模式。
在SRS模式下，能够参与发送参考信号的天线数量越多，信道估计就越准，进而能获得的速率越高；天线数量相同时，SA模式比NSA模式更快地完成信道估计，提高网络体验感。
目前各大运营商均提出来了5G NR支持SRS的功能要求，例如中国移动在其发布的《中国移动5G终端产品白皮书》中明确提出，N41/79必须支持SRS功能(1T2R或2T4R)；中国联通在其发布的《中国联通5G终端白皮书》中明确要求，N78必须支持SRS 1T4R和2T4R天线Ant轮发；中国电信在其 发布的《中国电信5G全网通终端需求白皮书》中提出，支持1端口和2端口SRS发射，支持天线Ant切换，推荐N78频段下支持4天线Ant轮发，即SRS 1T4R和2T4R。

通过在通信设备上设置该射频收发系统，提高了射频收发系统的集成度，减小了射频收发系统中各器件占用基板的面积，同时还可以简化了射频PA Mid器件10、射频L-DRX模块的供电、逻辑控制以及PCB的布局布线，节约了成本。
