如图1所示，前端模块400包括第一收发单元401、第二收发单元402、双讯器406、低通滤波器403、高频滤波器404以及天线405，天线405与双讯器406相连接，所双讯器406设置有两个支路，一个支路与第二收发单元402相连接；另一个支路分为两个子支路，一个子支路与低通滤波器403相连接，另一个子支路与高频滤波器404相连接。低通滤波器403和高频滤波器404均连接于第一收发单元401上，以使得低通滤波器403和高频滤波器404并联于第一收发单元401和双讯器406之间。在本实施例中，低通滤波器403的截止频率优选为780MHz，高频滤波器404的截止频率780MHz。也就是说，对于低通滤波器403，低于780MHz的载波信号可以通过低通滤波器403，高于等于780MHz的载波信号无法通过低通滤波器403。对于高频滤波器404，低于等于780MHz的载波信号无法通过高频滤波器404，高于780MHz的载波信号可以通过高频滤波器404。此外，前端模块400还包括电阻407，电阻407一端连接于第一收发单元401上，另一端接地。其中，电阻407的阻值优选为50欧姆。
如图1所示，载波聚合模块300若干双工位器302、四工位器303以及控制开关301；双工位器302和四工位器303并联于射频收发器200和前端模块400之间，并通过双工位器302和/或四工位器303将前端模块400接收到的载波传输值射频收发器200；控制开关301一端连接射频收发器200，另一端分别连接双工位器302和四工位器303，并通过控制开关301将射频收发器200发送的载波信号传输至双工位器302或四工位器303。也就是说，射频收发器200发送的低频载波信号通过控制开关301和低频载波信号对应的双工位器302或者四工位器303传输至前端模块400，并通过前端模块400发送至基站。同时，前端模块400接收到基站发送的若干载波信号通过载波聚合模块300同步发送至射频收发器200。
在本实施例中，双工位器302为3个，三个双工位器302并联于射频收发器200与前端模块400之间，并且三个双工位收发器并联于控制开关301和前端模块400之间。也就是说，对于上行信号，控制开关301、三个双工位器302和前端模块400形成三个通路；对于下行信号，前端模块400、三个双工位器302和射频收发器200形成三个通路。其中，三个双工位器302分别为B12双工位器、B5双工位器以及B1双工位器。此外，四工位器303与控制开关301之间配置有两路通讯信号，同时四工位器303与射频收发器200之间也配置有两路通讯信号。其中，四工位器303可以为B2-B4四工位器。
进一步，载波聚合模块300还包括功率放大器304，功率放大器304连接于射频收发器200和控制开关301之间，并将射频收发器200发送的载波信息放大后发送至控制开关301。其中，功率放大器304用于接收并放大射频收发器200发送的载波信号，并将放到后的载波信号传输给控制开关301，以通过控制开关301和载波信号对应的双工器发送至前端模块400，并通过前端模块400的天线405发送给基站。此外，载波聚合模块300还包括滤波器305，滤波器305连接于前端模块400与射频收发器200之间，并与双工位器302和四工位器303并联。其中，滤波器305为B29滤波器305，由于所B29只有下行信号，其频率为717-728MHz，从而滤波器305均均有下行通路，即前端模块400与滤波器305相连接，滤波器305与射频收发器200相连接，以形成由前端模块400至射频收发器200的单向通路，并且滤波器305不与控制开关301相连接。
同时在一些实施例中，四工位器303和B1双工位器302均与前端模块400中的第二收发单元402相连接，B5双工位器、B12双工位器以及B29滤波器均与第一收发单元401相连接。也就是说，第一收发单元401用于收发B5载波信号，接收B29载波信息以及发送B12载波信号；第二收发单元402用于收发B2/B4载波信号，并用于收发B1载波信号。
在一些实施例中，控制开关301为单刀X掷的开关。当然，在一些实施例中，控制开关301还可以为双刀X掷的开关。并且，载波聚合模块300还可以包括低噪声放大器，低噪声放大器可以连接于控制开关301与功率放大器304之间，也可以连接于射频收发器200与功率放大器304之间等。
此外，为了进一步说明本申请提供的载波聚合装置，下面结合几种低频载波信号的聚合过程对载波聚合装置加以说明。
B5载波信号与B29载波信号的聚合过程可以为：根据3GPP36.101定义，B29载波信号只有下行信号，频率为717-728MHz，B5载波信号的上行频率为824-849MHz，下行频率为869-894MHz，那么B29载波信号和B5载波信号均通过双讯器后，B29载波信号通过低通滤波器传输到第一收发单元，B5载波信号通过高频滤波后传输至第一收发单元，第一收发单元将B29载波信号经过B29滤波器传输至射频收发器，第一收发单元将B5载波信号经过B5双工器传输至射频收发器，射频收发器将B5载波信号变频到CPU解调信息的低频载波信号，从而实现了B5载波信号和B29载波信号的聚合。本实施例通过低通滤波器和高频滤波器对B5载波信号和B29载波信号进行过滤，并且低通滤波器和高频滤波器对于小于1GHz的信号插损小，一般只有0.2-0.3dB，这样可以以较小的损耗实现B5载波信号和B29载波信号两个低于1GHz的低频段的载波信号的聚合。
B5载波信号与B12载波信号的聚合过程可以为：根据3GPP36.101定义，B12载波信号的上行频率为699-716MHz，下行频率为729-746MHz，B5载波信号的上行频率为824-849MHz，下行频率为869-894MHz，那么B12载波信号和B5载波信号均通过双讯器后，B12载波信号通过低通滤波器传输到第一收发单元，B5载波信号通过高频滤波后传输至第一收发单元，第一收发单元将B12载波信号经过B12双工器传输至射频收发器，第一收发单元将B5载波信号经过B5双工器传输至射频收发器，射频收发器将B5载波信号变频到CPU解调信息的低频载波信号，从而实现了B5载波信号和B29载波信号的聚合。本实施例通过低通滤波器和高频滤波器对B5载波信号和B29载波信号进行过滤，并且低通滤波器和高频滤波器对于小于1GHz的信号插损小，一般只有0.2-0.3dB，这样可以以较小的损耗实现B5载波信号和B29载波信号两个低于1GHz的低频段的载波信号的聚合。
此外，本申请提供的载波聚合装置还可以实现B5A-29A-2A-4A的4载波的载波聚合，也可以实现B5A-29A-2A-4A-B7/B30的大于5载波的载波聚合。当然，当实现B5A-29A-2A-4A-B7/B30载波聚合时，载波聚合装置的载波聚合模块中还可以包括B7/B30双工位器，并且B7/B30双工位器与载波聚合模块中的其他双工位器和四工位器并联。
基于上述的载波聚合装置，本实施例还提供了一种终端设备，所述终端设备配置有上述实施例所述的载波聚合状态。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
