Description

一种移动终端及其射频架构
技术领域
本发明涉及移动终端领域，尤其涉及的是一种移动终端的射频架构。
背景技术
目前手机的发展由2G到3G和4G，随着模式的增加，频段也增加很多，特别是对于做海外方案的项目，4G FDD频段会很多，这对于天线来说，难度会增加很多。
另外一方面，随着手机ID越来越趋于金属化，而金属化则意味着天线环境越来越差。但海外项目基本上都有多个低频频段，这对于信号来说，频段越低，波长越长，天线需要的面积就越大，而多个低频频段意味着需要多个低频的天线，这对于金属天线来说，对手机ID的限制就很大。
现有手机的射频结构，一般都是通过切换开关来实现，就是上下都有低频天线，通过切换频段来选择天线，例如，专利文献CN102448129A所公开的LTE系统的模式切换方法及装置，在该LTE系统中，LTE的主集通道采用第一天线开关进行分集频段的切换，LTE的分集通道、3G通道及2G通道通过第二天线开关进行模式与频段的切换；即第一天线开关用于将当前工作模式切换为LTE主集通路，第二天线开关用于将当前工作模式切换为2G通道、3G通道或LTE分集通道；LTE系统的主集单端采用第一天线开关和第一天线，即第一天线只给LTE的主集使用；相应的射频信号转换为基带信号后，通过基带物理层进行天线开关的切换控制和模式切换，对本领域技术人员来说，具体的操作控制手段与专利文献CN102448129A所公开的LTE系统的模式切换方法及装置相类似，以及基带物理层触发射频开关的开启与闭合操作，均属于本领域的现有技术，在此不再赘述；但是，增加额外的切换开关就相当于增加器件，而增加器件就会增加损耗，有时候所增加的损耗基本抵消了天线的作用，同时天线开关的价格也比较高，对主板布局要求也较高，不适合快速设计。
因此，现有技术尚有待改进和发展。
发明内容
为解决上述技术问题，本发明提供一种移动终端射频架构，无需增加额外的切换开关。
同时，本发明还提供一种移动终端，对主板布局要求低，适合快速设计。
本发明的技术方案如下：一种移动终端射频架构，由收发器、主射频开关、分集开关、主天线和分集天线组成；收发器经由主射频通路连通主射频开关，收发器经由分集通路连接分集开关，band20/band17/band13低频频段的主集天线信号经由分集通路调试，band20/band17/band13低频频段的分集天线信号经由主射频通路调试。
所述的移动终端射频架构，其中：所述主天线的低频频段用于调试850/900MHz频段。
所述的移动终端射频架构，其中：所述分集天线的低频频段用于调试700/800MHz频段。
所述的移动终端射频架构，其中：600-850MHz低频频段的主集天线信号经由分集通路调试，600-850MHz低频频段的分集天线信号经由主射频通路调试。
一种移动终端，包括基于天线的射频架构，其中：所述射频架构设置为上述中任一项所述的移动终端射频架构。
本发明所提供的一种移动终端及其射频架构，通过调整主集和分集的通路来实现天线的切换，既不需要增加额外的切换开关，也不会增加损耗，同时，对主板布局要求还低，非常适合快速设计。
附图说明
图1是本发明移动终端射频架构的原理图。
具体实施方式
以下将结合附图，对本发明的具体实施方式和实施例加以详细说明，所描述的具体实施例仅用以解释本发明，并非用于限定本发明的具体实施方式。
如图1所示，图1是本发明移动终端射频架构的原理图，以4G FDD频段的手机为例，该手机的射频构架由收发器101、主射频开关102、分集开关103、主天线104和分集天线105组成；收发器101经由主射频通路106连通主射频开关102，收发器101经由分集通路108连通分集开关103。
在正常的射频构架下，所有射频的主集天线信号都走主射频开关102，例如，2G频段的低频GSM850和GSM900，又如，4G频段的低频band20、band17、band13以及band5，如果所有频段的主集天线信号都走主天线104，势必会导致主天线104的低频带宽需要很宽，由此对天线环境要求就高，这样一来就会对手机ID产生很多限制，甚至是做不出来。
实际上，任何一个4G频段都既有主集天线又有分集天线，分集天线只是起到辅助主集天线的作用，其重要性自然不如主集天线，本发明正是利用了这一特性，为避免多个低频都集中在主天线104上，特意将band20/band17/band13低频频段的主集天线信号经由分集通路108调试，而band20/band17/band13低频频段的分集天线信号经由主射频通路106调试，这种由主射频通路106走分集天线信号、分集通路108走主集天线信号的做法，一方面，不用额外增加天线开关，降低成本，减少损耗，另一方面，降低了主天线104对环境的要求，对主板布局要求低，非常适合快速设计。
在本发明移动终端射频架构的优选实施方式中，所述主天线104的低频频段用于调试850/900MHz频段，和/或，所述分集天线105的低频频段用于调试700/800MHz频段，提升了band20/band17/band13频段的主集天线性能，保证了正常通话和上网效果。
其次，4G FDD低频频段并不局限于band20/band17/band13频段，也可以是600-850MHz之间的频段。
应当理解的是，以上所述仅为本发明的较佳实施例而已，并不足以限制本发明的技术方案，对本领域普通技术人员来说，在本发明的精神和原则之内，可以根据上述说明加以增减、替换、变换或改进，例如，本发明不局限于4D FDD频段，还可以用于2G或3G频段，而所有这些增减、替换、变换或改进后的技术方案，都应属于本发明所附权利要求的保护范围。
