Description

射频架构及终端设备 技术领域
本发明涉及通信领域，尤其涉及一种射频架构及终端设备。
背景技术
在非独立组网(non-standalone，NSA)方案中，由于MHB PAMID(Middle and high Band PA Module integrated duplexer，Middle and high Band Power Amplifier Module integrated duplexer，中高频功率放大器模组)和N41模组均支持新无线(New Radio，NR)性能，所以需要更高的电压供电，可以选择分别外挂直流变直流电源(Direct Current Source，DCDC)供电；而LB PAMID(Low Band PA Module integrated duplexer，低频PA模组)只支持LTE性能，因此，可以使用电源管理集成电路(Power Management IC，PMIC)供电。但是，因为MHB PAMID和N41模组需要更高的电压供电，即性能要求比较高，从而增加射频架构的复杂性。
发明内容
本发明实施例提供了一种射频架构及终端设备，用于通过对4G和5G双连接技术方案的架构进行合理优化，减小PA元器件成本，达到降成本的目的。
有鉴于此，本发明第一方面提供了一种射频架构，可以包括：
第一功率放大器PA模组，用于支持特定频段，新无线NR/长期演进LTE中的中高频段MHB；
第二功率放大器PA模组，用于支持LTE中的低频段LB；
第三功率放大器PA模组，用于支持LTE中的中频段MB；
第一电源与所述第一PA模组连接，用于为所述第一PA模组提供电源；
第二电源与所述第二PA模组连接，用于为所述第二PA模组提供电源；
第三电源与所述第三PA模组连接，用于为所述第三PA模组提供电源。
本发明第二方面提供了一种终端设备，可以包括如本发明第一方面所述的射频架构。
从以上技术方案可以看出，本发明实施例具有以下优点：
在本发明实施例中所提供的射频架构，可以包括：第一功率放大器PA模组，用于支持特定频段，新无线NR/长期演进LTE中的中高频段MHB；第二功率放大器PA模组，用于支持LTE中的低频段LB；第三功率放大器PA模组，用于支持LTE中的中频段MB；第一电源与所述第一PA模组连接，用于为所述第一PA模组提供电源；第二电源与所述第二PA模组连接，用于为所述第二PA模组提供电源；第三电源与所述第三PA模组连接，用于为所述第三PA模组提供电源。因为特定频段可以由第一PA模组来支持，不需要单独外挂特定PA模组，但为了支持M+H ENDC要求，可以外挂支持LTE中的中频MB频段的第三PA模组，而第三PA模组的成本小于特定PA模组，所以，通过对4G和5G双连接技术方案的架构进行合理优化，减小PA元器件成本，达到降成本的目的。

具体实施方式
本发明实施例提供了一种射频架构及终端设备，用于通过对4G和5G双连接技术方案的架构进行合理优化，减小PA元器件成本，达到整机降成本的目的。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，都应当属于本发明保护的范围。
下面可以先对本发明实施例中所涉及的NSA方案做个简要的说明，如下所示：
5G移动带宽增强(Enhanced Mobile Broadband，eMBB)应用场景下，几何式增加的海量数据需求对个人终端设备数据通信能力提出了前所未有的要求，5G NSA(non-standalone，非独立组网)和SA(standalone，独立组网)两大部署方案在提升通信速率方面都有关键方案加持，比如NSA下的1T4R(1路发射4路接收)和SA下的2T4R(2路发射4路接收)和1T4R都是为了提升通讯速率，尤其是下行通信速率；因为个人大数据应用比如短视频、视频电影等应用，对于下行速率要求更高。
由于目前5G基站覆盖范围小，所以覆盖长期演进(Long Term Evolution，LTE)相同面积，需要的5G基站数量在前者的3倍以上，建网成本骤然增加。由于全球范围内经济发展不均，以及各国不同的4G到5G演进策略，所以全球范围内ENDC(E-UTRA NR Dual Connectivity、4G和5G双连接技术)方案将会在相当长的一段时间内成为重要的5G覆盖方案，即采用4G和5G双连接的方案保证在5G信号不稳定或者未覆盖区域的信号连续性。ENDC是4G和5G双连接，目前全球范围内LTE存在LB(Low Band，低频)/MB(Middle Band，中频)/HB(High Band，高频)等多个频段，5G也存在LB/MB/HB/SUB6G等多个频段，所以二者之间任意组合会出现很多种ENDC方案，比如常见LB+LB，LB+MB，LB+HB，MB+HB，LB+SUB6G，MB+SUB6G，HB+SUB6G。目前国内主要要求MB+HB(B1/3/39+N41)，LB+SUB6G，MB+SUB6G，HB+SUB6G。
当前典型的射频(Radio Frequency，RF)架构如图1所示：其中NR/LTE MHB PAMID(Middle and high Band PA Module integrated duplexer，Middle and high Band Power Amplifier Module integrated duplexer，中高频功率放大器模组)支持MB和HB的LTE和新无线(New Radio，NR)，LB PAMID(LB PA Module integrated duplexer，低频PA模组)支持LTE特性；由于其中NR/LTE MHB PAMID不能支持MB和HB同时发射，为了支持M+H ENDC要求，需要外挂一颗单N41PA模组。
但是，两个DCDC带来成本增加明显，而且，N41PAM(Power Amplifier Module，PA模组，功率放大器模组)本身成本也较高。
下面介绍下本发明实施例中使用的术语，如下所示：
DCDC电源，Direct Current Source，直流变换器，表示的是将某一电压等级的直流电源变换其他电压等级直流电源的装置。DC/DC按电压等级变换关系分升压电源和降压电源两类，按输入输出关系分隔离电源和无隔离电源两类。例如：车载直流电源上接的DC/DC变换器是把高压的直流电变换为低压的直流电。
PMIC电源，Power Management IC，电源管理集成电路，它是用来管理主机系统中的电源设备，常用于手机以及各种移动终端设备。
高频段(High Band，HB)，中频段(Mid Band，MB)，低频段(Low Band，LB)，N41为5G频段。其中，N41频段范围为2496MHz-2690MHz，HB频段范围为2300MHz-2690MHz，MB频段范围为1710MHz-1980MHz， LB频段范围为663MHz-915MHz。SUB6G是指5G频段，工作频率在450MHz-6000MHz的6G以下频段。
功率放大器(power amplifier，PA)，简称“功放”，指在给定失真率条件下，能产生最大功率输出以驱动某一负载的放大器。利用三极管的电流控制作用或场效应管的电压控制作用将电源的功率转换为按照输入信号变化的电流。例如扬声器，功率放大器在整个音响系统中起到了“组织、协调”的枢纽作用，在某种程度上主宰着整个系统能否提供良好的音质输出。而PA在当今物联网领域广泛应用的时代也是起到很大的辅助性。
其中，功率放大器通常包括3部分：前置放大器、驱动放大器、末级功率放大器。前置放大器起匹配作用，其输入阻抗高(不小于10kΩ)，可以将前面的信号大部分吸收过去，输出阻抗低(几十Ω以下)，可以将信号大部分传送出去。同时，它本身又是一种电流放大器，将输入的电压信号转化成电流信号，并给予适当的放大。驱动放大器起桥梁作用，它将前置放大器送来的电流信号作进一步放大，将其放大成中等功率的信号驱动末级功率放大器正常工作。如果没有驱动放大器，末级功率放大器不可能送出大功率的声音信号。末级功率放大器起关键作用。它将驱动放大器送来的电流信号形成大功率信号。
在本发明实施例中，如图2A所示，为本发明实施例中提供的射频架构的一个实施例示意图，可以包括：

RF架构410可用于收发信息或通话过程中，信号的接收和发送，特别地，将基站的下行信息接收后，给处理器480处理；另外，将设计上行的数据发送给基站。通常，RF架构410包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器(Low Noise Amplifier，LNA)、双工器等。此外，RF架构410还可以通过无线通信与网络和其他设备通信。上述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统(Global System of Mobile communication，GSM)、通用分组无线服务(General Packet Radio Service，GPRS)、码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、长期演进(Long Term Evolution，LTE)、电子邮件、短消息服务(Short Messaging Service，SMS)等。
存储器420可用于存储软件程序以及模块，处理器480通过运行存储在存储器420的软件程序以及模块，从而执行手机的各种功能应用以及数据处理。存储器420可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器420可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
输入单元430可用于接收输入的数字或字符信息，以及产生与手机的用户设置以及功能控制有关的键信号输入。具体地，输入单元430可包括触控面板431以及其他输入设备432。触控面板431，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板431上或在触控面板431附近的操作)，并根据预先设定的程式驱动相应的连接装置。可选的，触控面板431可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器480，并能接收处理器480发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板431。除了触控面板431，输入单元430还可以包括其他输入设备432。具体地，其他输入设备432可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆等中的一种或多种。
显示单元440可用于显示由用户输入的信息或提供给用户的信息以及手机的各种菜单。显示单元 440可包括显示面板441，可选的，可以采用液晶显示器(Liquid Crystal Display，LCD)、有机发光二极管(Organic Light-Emitting Diode,OLED)等形式来配置显示面板441。进一步的，触控面板431可覆盖显示面板441，当触控面板431检测到在其上或附近的触摸操作后，传送给处理器480以确定触摸事件的类型，随后处理器480根据触摸事件的类型在显示面板441上提供相应的视觉输出。虽然在图4中，触控面板431与显示面板441是作为两个独立的部件来实现手机的输入和输入功能，但是在某些实施例中，可以将触控面板431与显示面板441集成而实现手机的输入和输出功能。
手机还可包括至少一种传感器450，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板441的亮度，接近传感器可在手机移动到耳边时，关闭显示面板441和/或背光。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；至于手机还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
音频电路460、扬声器461，传声器462可提供用户与手机之间的音频接口。音频电路460可将接收到的音频数据转换后的电信号，传输到扬声器461，由扬声器461转换为声音信号输出；另一方面，传声器462将收集的声音信号转换为电信号，由音频电路460接收后转换为音频数据，再将音频数据输出处理器480处理后，经RF架构410以发送给比如另一手机，或者将音频数据输出至存储器420以便进一步处理。
WiFi属于短距离无线传输技术，手机通过WiFi模块470可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图4示出了WiFi模块470，但是可以理解的是，其并不属于手机的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器480是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器420内的软件程序和/或模块，以及调用存储在存储器420内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器480可包括一个或多个处理单元；优选的，处理器480可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器480中。
手机还包括给各个部件供电的电源490(比如电池)，优选的，电源可以通过电源管理系统与处理器480逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
尽管未示出，手机还可以包括摄像头、蓝牙模块等，在此不再赘述。需要说明的是，在本发明实施例中，RF架构410为上述实施例中图2A-图2I任一所示实施例中的射频架构。
所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统，装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
