在实现本发明过程中， 发明人发现现有技术中至少存在如下问题： 通过 为数据卡配备天线底座虽然在一定程度上提高了天线增益， 但是由于底座的 特定形状结构的局限， 天线增益的提高也有限； 若还要增加天线增益， 则需 要增加底座的高度， 而桌面型设备的高度有一定限制， 不能太高， 所以此种 设计方案对于改善数据卡的室内覆盖的能力有限。 因此， 现有技术中釆用 1T2R的射频设计的数据卡具有上行发射增益小 ,覆盖区域小，在室内信号弱 , 穿墙能力差等缺陷； 而且受到 USB电源供电限制等问题， 如何在数据卡上实 现 2T2R即具有两个发射通道和两个接收通道的射频设计目前尚无解决方案。 发明内容

本发明实施例提供的数据接发处理设备、数据接发处理设备底座及系统， 通过新增一条数据发射通道， 实现数据接发处理设备的 2T2R射频设计， 增 加上行发射增益， 扩大覆盖区域， 降低基站部署成本。 附图说明
图 1为本发明数据接发处理系统实施例一结构示意图；
图 2为本发明数据接发处理系统实施例二结构示意图。 具体实施方式
下面结合附图和具体实施例进一步说明本发明实施例的技术方案。
本发明各实施例是针对现有技术中数据卡釆用 1T2R的射频设计时具有 上行发射增益小， 覆盖区域小， 在室内信号弱， 穿墙能力差等缺陷， 提供一 种实现数据卡 2T2R 即两个发射通道和两个接收通道的解决方案， 增强天线 增益， 提高信号强度。
图 1为本发明数据接发处理系统实施例一结构示意图， 如图 1所示， 在 该系统中包括数据接发处理设备 1 和数据接发处理设备底座 2, 其中数据接 发处理设备 1可以为通用串行总线（ Universal Serial BUS； 以下简称： USB ) 数据卡， 相应地， 数据接发处理设备底座 2可以为 "USB cradle" 。 如图 1 所示， 数据接发处理设备 1 包括串接的射频收发器模块即 RF11和基带芯片 处理模块即 BB12, 与 RF11连接的有两路第一数据接收通道和两路数据发射 通道， 两路数据发射通道分别为第一数据发射通道和第二数据发射通道。 数 据接发处理设备 1还包括两条第一天线 13 , 每条第一天线 13均可以完成数 据的接收和发射。在每条第一天线 13与数据接收通道和数据发射通道之间还 设置有第一接发转换模块 14, 数据接发处理设备 1包括两个第一接发转换模 块 14。 如图 1中箭头的指示方向可知， 数据接发处理设备 1中位置于第一接 发转换模块 14和 RF11之间的两路第一数据接收通道中， 每路第一数据接收 通道包括从第一接发转换模块 14至 RF11 串接的带通滤波器（BPF )和平衡 转换器（ Balun ) ;数据接发处理设备 1中位置于第一接发转换模块 14和 RF11 之间的第一数据发射通道包括从 RF11至第一接发转换模块 14依次串接的平 衡转换器（Balun ) 、 带通滤波器（ BPF ) 、 功率放大器（ PA )和低通滤波器 ( LPF ) , 第二数据发射通道包括从 RF 11至第一接发转换模块 14串接的平 衡转换器（Balun )和带通滤波器（ BPF ) 。 从图 1中可以看出， 本实施例是 在现有两路数据接收通道和一路数据发射通道的基础上， 增设一路数据发射 通道， 在新增的数据发射通道中可以仅包括现有数据发射通道中的一部分， 例如本实施例中仅包括原有数据发射通道中的平衡转换器（Balun )和带通滤 波器（BPF ) , 而原有数据发射通道中后续元件例如功率放大器（PA )和低 通滤波器（LPF )将被设置在 "USB cradle" 中， 通过数据卡和 "USB cradle" 的配合实现数据卡的 2T2R的射频设计。
数据接发处理设备 1中，每个第一接发转换模块 14均设置有与数据接发 处理设备底座 2连接的第一天线连接端子， 当数据接发处理设备 1插入数据 接发处理设备底座 2中时， 两个第一天线连接端子可以分别与数据接发处理 设备底座 2中的对应的天线连接端子连接， 这样便可以使用数据接发处理设 备底座 2中的天线完成数据的接收和发射。 如图 1所示， 每个第一接发转换 模块 14均包括两个串接的第一切换开关（Switch ) , 其中一个第一切换开关 与第一天线 13连接，另一个第一切换开关与数据发射通道和数据接收通道连 接。 第一接发转换模块 14上的第一天线连接端子可以设置在与第一天线 13 连接的第一切换开关上。
为了达到数据接发处理设备与数据接发处理设备底座配合实现 2T2R,要 在数据接发处理设备 1 中的 BB12上引出两个接线端子， 分别为双发触发接 收端子和控制端子， 所述两个接线端子在 BB12上也可共用同一接线端子， 其中双发触发接收端子用于与数据接发处理设备底座 2连接、 触发第二数据 发射通道工作， 也就是说， 双发触发接收端子与数据接发处理设备底座 2中 的触发模块连接后， 将接收到触发模块发送的触发信号， BB12在接收到该触 发信号后便启用新增的第二数据发射通道， 此时数据接发处理设备 1 中的两 路数据接收通道和两路数据发射通道均处于工作状态， 实现了 2T2R的射频 设计。 当然由于本实施例中， 数据接发处理设备 1 中的第二数据发射通道中 仅包括能够完成数据发射的部分元件， 另一些元件被设置于数据接发处理设 备底座 2中， 因此 BB12引出的控制端子用于控制数据接发处理设备底座 2 使其配合数据接发处理设备 1 实现新增数据发射通道的正常工作。 由于数据 接发处理设备 1插入数据接发处理设备底座 2后， 将使用数据接发处理设备 底座 2中的天线进行数据的接收和发射， 因此将 BB12通过控制端子向数据 接发处理设备底座 2发送数据接发切换的控制信号， 使得数据接发处理设备 底座 2在控制信号的作用下， 在规定时间内将工作模式切换到数据发射状态 上， 以便数据接发处理设备 1通过第二数据发射通道发射的数据能够通过数 据接发处理设备底座 2成功发射出去； 并在规定时间内将工作模式切换到数 据接收状态上， 以便能够成功地接收外界发送的数据。 上述所述的规定时间 为软件控制 BB进行收发切换的固化时间， 一般应控制在 50微秒以内。
本实施例提供的数据接发处理设备， 通过在其中新增数据发射通道， 配 合设置与数据接发处理设备底座对应天线的连接端子， 并通过基带芯片引出 的用于触发新增数据发射通道工作的双发触发接收端子和用于对数据接发处 理设备底座进行接发控制的控制端子， 在 USB数据卡中实现双发射通道， 增 加上行发射增益， 扩大覆盖区域， 降低基站部署成本。
如图 1 所示， 本实施例还提供一种数据接发处理设备底座 2, 包括两条 第二天线 21 , 第二天线 21上设置有用于与数据接发处理设备 1的第一天线 连接的第二天线连接端子；数据接发处理设备底座 2还包括双发触发模块 22, 双发触发模块 22上设置有用于为数据接发处理设备 1提供双发触发信号的双 发触发端子。 双发触发模块 22即为图中所示的 "2T Trigger" , 本发明各实 施例中提供的数据接发处理设备底座中的 "2T Trigger" 可以是现有具有抬高 电平功能的器件， 或者是一个单片机的外围管脚等， 具体地为可以釆用一个 单片机检测 USB电路，当 USB数据卡插入数据接发处理设备底座之后， "2T Trigger"检测到 USB信号后触发单双发切换； 还可以釆用电流脉冲方案， 即 当 USB数据卡插入数据接发处理设备底座之后， "2T Trigger" 检测到 USB 信号， 然后主动向 USB数据卡发射一串脉冲码流， BB12检测 USB脉冲码流 触发单双发切换， 硬件实现可以通过小型的 IC集成电路实现； 另外还可以釆 用探针方式， BB12通用 10 口接口（General-Purpose 10 ports; 简称： GPIO) 检测是否连接底座等。 当数据接发处理设备 1插入数据接发处理设备底座 2 后， 数据接发处理设备 1 中从 BB引出的双发触发接收端子与双发触发模块 22上的双发触发端子连接， 双发触发模块 22向 BB发送双发触发信号，指示 数据接发处理设备 1启动新增的第二数据发射通道。
数据接发处理设备底座 2还包括第二接发转换模块 23 , 第二接发转换模 23块包括与一条第二天线 21 串接的第二切换开关 24和第三切换开关 25,第 三切换开关 25上设置有第二天线连接端子和用于接收数据接发处理设备 1发 送的接发控制信号的控制接收端子； 第二切换开关 24和第三切换开关 25之 间设置有并联的第二数据接收通道和第三数据发射通道。第二切换开关 24与 一条第二天线 21连接， 第三切换开关 25通过第二天线连接端子与数据接发 处理设备 1中的一个第一接发转换模块连接； 数据接发处理设备底座 2中的 另一条第二天线通过设置在其上的第二天线连接端子与数据接发处理设备 1 的另一个第一接发转换模块连接。 位于第二切换开关 24和第三切换开关 25 之间设置的第二数据接收通道和第三数据发射通道在同一时刻仅能是其中一 个通道处于工作状态， 二者的切换可以在第三切换开关 25上完成， 第三切换 开关 25通过其上的控制接收端子接收数据接发处理设备 1发送的切换控制信 号完成第二数据接收通道和第三数据发射通道之间的切换。 所述第二数据接 收通道包括低噪声放大器（LNA ) , 所述第三数据发射通道从第三切换开关 25至第二切换开关 24包括串接的功率放大器（PA )和低通滤波器（LPF ) , 由此可得到， 第三数据发射通道中和第二数据发射通道中的元件之和与第一 数据发射通道中的元件相同。
由于将功率放大器（ PA )设置在数据接发处理设备底座 2中， 因此数据 接发处理设备底座 2中可以包括一个电源模块即图 1中的" Power Module" 26 用于为该功率放大器（PA )提供电源。 数据接发处理设备底座 2应包括一个 用于供数据接发处理设备 1插入的插入接口，例如本实施例中釆用 USB接口 方式， "USB Connector" 27为 USB数据卡提供插入接口。 当然电源模块 26 还可以为 "USB Connector" 27提供所需电源。
本实施例提供的数据接发处理设备底座， 在数据接发处理设备插入时为 数据接发处理设备提供指示使用新增数据发射通道的双发触发信号或触发数 据接发处理设备产生双触发信号， 并在数据接发处理设备发送的控制信号作 用下完成数据接收和发射的切换， 配合数据接发处理设备实现 2T2R, 以便增 强数据卡的增加上行发射增益， 扩大覆盖区域， 并可以降低基站部署成本。
如图 1所示， 本实施例提供的数据接发处理系统包括数据接发处理设备 1和数据接发处理设备底座 2,数据接发处理设备 1包括串接的射频收发器模 块即 RF11和基带芯片处理模块即 BB12, 和与 RF11连接的两路第一数据接 收通道和第一数据发射通道， 以及设置于两条第一天线与所述两路第一数据 接收通道和所述第一数据发射通道之间的两个第一接发转换模块 14, 第一接 发转换模块 14与 RF11之间还设置有第二数据发射通道； 第一接发转换模块 14上设置有与数据接发处理设备底座 2连接的第一天线连接端子， BB12上 设置有用于与数据接发处理设备底座 2连接、 触发所述第二数据发射通道工 作的双发触发接收端子和用于对数据接发处理设备底座 2进行接发控制的控 制端子； 所述第二数据发射通道从 RF11至第一接发转换模块 14包括串接的 平衡转换器（Balun )和带通滤波器（ BPF ) 。
数据接发处理设备底座 2包括两条第二天线 21 , 第二天线 21上设置有 用于与数据接发处理设备第一接发转换模块 14连接的第二天线连接端子；还 包括双发触发模块 22,双发触发模块 22上设置有用于为数据接发处理设备 1 提供双发触发信号的双发触发端子； 还包括第二接发转换模块 23 , 第二接发 转换模块 23包括与一条第二天线 21串接的第二切换开关 24和第三切换开关 25,第三切换开关 25上设置有所述第二天线连接端子和用于接收所述数据接 发处理设备 1发送的接发控制信号的控制接收端子；第二切换开关 24和第三 切换开关 25之间设置有并联的第二数据接收通道和第三数据发射通道，所述 第二数据接收通道包括低噪声放大器（LNA ) , 所述第三数据发射通道从所 述第三切换开关至所述第二切换开关包括串接的功率放大器（PA )和低通滤 波器 ( LPF ) 。

本系统中涉及的数据接发处理设备和数据接发处理设备底座可以分别釆 用以上实施例提供的数据接发处理设备和数据接发处理设备底座， 具体结构 不再赘述， 以下通过数据接收及发射流程详细介绍本系统是如何实现数据卡 2T2R射频设计的。
如图 1所示， 数据接发处理设备 1中的 "SD Card Reader & USB Hug" 是一个支持多 USB口互连和 SD读卡器的器件， 数据接发处理设备 1通过它 与数据接发处理设备底座 2中的 USB连接器（ USB Connector )连接， 同时 数据接发处理设备 1 中基带 BB12芯片引出的两个管脚分别与数据接发处理 设备底座 2中的 "Switch" 和 "2T Trigger" 连接， 其中连接 "2T Trigger" 的 管脚用于检测数据接发处理设备 1是否插入数据接发处理设备底座 2即 "USB Cradle" 中， 如果是插入 "USB Cradle" 中， 则相应管脚电平抬高， 否则是低 电平； 具体地为可以釆用一个单片机检测 USB电路， 当 USB数据卡插入数 据接发处理设备底座之后， "2T Trigger" 检测到 USB信号后触发单双发切 换；还可以釆用电流脉冲方案， 即当 USB数据卡插入数据接发处理设备底座 之后， "2T Trigger" 检测到 USB信号， 然后主动向 USB数据卡发射一串脉 冲码流， BB12检测 USB脉冲码流触发单双发切换， 硬件实现可以通过小型 的 IC 集成电路实现； 另外还可以釆用探针方式， BB12 通用 10 口接口 (General-Purpose 10 ports;简称： GPIO)检测是否连接底座等。而连接 "Switch" 的管脚用于控制 "USB Cradle" 中的开关控制， 做收发切换。 上述实施中， BB12 引出的两个管脚即为上述实施例中描述的双发触发接收端子和控制端 子。 当数据接发处理设备 1插入数据接发处理设备底座 2中后， 对应的天线 连接端子也将相互连接起来， 数据接发处理系统便可使用数据接发处理底座 中的两天线进行数据的接收和发射。
如图 1所示， 数据接发处理系统中与 RF11连接的从上至下数据通道分 别如下： BB12完成数据的处理后将待发射数据发送给 RF11 , 发射数据按照 图中箭头方向在第一路数据通道上依次经过 "Balun" 和 BPF后， 经过两个 "Swtich" 后沿天线连接端子上传至数据接发处理底座中的第三切换开关 "Swtich" , 再经过 PA、 LPF后， 由第二切换开关 "Swtich" 向外界发射， 这是第一路数据发射通道； 另一路数据发射通道是数据经过图中第四路数据 通道依次经过 "Balun" 、 BPF, PA和 LPF后， 再经过两个 "Swtich" 沿天线 连接端子上传至数据接发处理设备底座中的天线后向外界发射， 这是第二路 数据发射通道。 对于数据接收通道， 数据由数据接发处理设备底座中的一条 天线接收后， 下传至数据接发处理设备底座中与连接有数据接发处理设备天 线的 "Swtich" 上， 再经过下一个 "Swtich" , 随后依次经过 BPF和 "Balun" 后传至 RF和 BB中， 实现数据接收， 这是第一路数据接收通道； 数据由数据 接发处理设备底座中的另一条天线接收后， 将数据发送至第二切换开关 "Swtich" 上， 经过 LNA后达到第三切换开关 "Swtich" , 然后下传至数据 接发处理设备中连接有数据接发处理设备另一条天线的 "Swtich" 上， 再经 过下一个 "Swtich" , 随后依次经过 BPF和 "Balun" 后传至 RF和 BB中， 实现数据接收， 这是第二路数据接收通道； 综上所述， 数据接发处理设备实 现了 2T2R的射频技术。 系统中如图所示， "Airplan mode switch" 为航空模 式切换开关， "Micro SD"为 SD卡连接器， "SPI Flash"为 SPI接口的 FLASH 器件。
本实施例提供的数据接发处理系统， 通过在数据接发处理设备和数据接 发处理设备底座中新增数据发射通道，在数据接发处理设备例如 USB数据卡 中实现双发射通道， 增加上行发射增益， 扩大覆盖区域， 降低基站部署成本。
图 2为本发明数据接发处理系统实施例二结构示意图， 如图 2所示， 在 该系统中包括数据接发处理设备 1 和数据接发处理设备底座 2, 其中数据接 发处理设备 1可以为 USB数据卡， 相应地， 数据接发处理设备底座 2可以为 "USB cradle" 。 如图 2所示， 数据接发处理设备 1包括串接的射频收发器模 块即 RF11和基带芯片处理模块即 BB12, 与 RF11连接的有两路第一数据接 收通道和两路数据发射通道， 两条数据发射通道分别为第一数据发射通道和 第二数据发射通道。 数据接发处理设备 1还包括两条第一天线 13 , 每条第一 天线 13均可以完成数据的接收和发射。 在每条第一天线 13与数据接收通道 和数据发射通道之间还设置有第一接发转换模块 14, 数据接发处理设备 1包 括两个第一接发转换模块 14。 如图 2中箭头的指示方向可知， 数据接发处理 设备 1中位置于第一接发转换模块 14和 RF11之间的两路第一数据接收通道 中， 每路第一数据接收通道包括从 RF 11至第一接发转换模块 14串接的平衡 转换器（Balun )和带通滤波器（ BPF ) ； 数据接发处理设备 1中位置于第一 接发转换模块 14和 RF11之间的第一数据发射通道包括从 RF11至第一接发 转换模块 14依次串接的平衡转换器（Balun )、 带通滤波器（ BPF )、 功率放 大器（PA )和低通滤波器（LPF ) , 新增的第二数据发射通道结构与第一数 据发射通道相同， 从 RF11至第一接发转换模块 14同样包括串接的平衡转换 器 ( Balun )、 带通滤波器（ BPF )、 功率放大器 ( PA )和低通滤波器（ LPF ) 。 从图 2中可以看出， 本实施例是在现有两条数据接收通道和一条数据发射通 道的基础上， 增设一条与现有数据发射通道结构相同的数据发射通道， 通过 数据卡和 "USB cradle" 的配合实现数据卡的 2T2R的射频设计。 数据接发处理设备 1中，每个第一接发转换模块 14均设置有与数据接发 处理设备底座 2连接的第一天线连接端子， 当数据接发处理设备 1插入数据 接发处理设备底座 2中时， 两个第一天线连接端子可以分别为数据接发处理 设备底座 2中的对应的天线连接端子连接， 这样便可以使用数据接发处理设 备底座 2中的天线完成数据的接收和发射。 如图 2所示， 每个第一接发转换 模块 14均包括两个串接的第一切换开关（Switch ) , 其中一个第一切换开关 与第一天线 13连接， 另一个第一切换开关与数据通道连接。 第一接发转换模 块 14上的第一天线连接端子可以设置在与第一天线 13连接的第一切换开关 上。
为了达到数据接发处理设备与数据接发处理设备底座配合实现 2T2R,要 在数据接发处理设备 1 中的 BB12上引出一个接线端子， 即双发触发接收端 子用于与数据接发处理设备底座 2连接、 触发第二数据发射通道工作， 也就 是说， 双发触发接收端子与数据接发处理设备底座 2中的触发模块连接后， 将接收到触发模块发送的触发信号， BB12在接收到该触发信号后便启用新增 的第二数据发射通道， 此时数据接发处理设备 1 中的两条数据接收通道和两 条数据发射通道均处于工作状态， 实现了 2T2R的射频设计。 当数据接发处 理设备 1插入数据接发处理设备底座 2中后， 便使用数据接发处理设备底座 2 中的天线作为数据接收和发射的接口。 本实施例中的数据接发处理设备与 上个实施例中提供的数据接发处理设备不同点在于， 本实施例中的数据接发 处理设备将完整的数据发射通道做到了 USB数据卡中， 而不是部分设置于底 座中， 在 USB 数据卡直接接入计算机时， 该路数据发射通道不工作， 而当 USB数据卡插入底座时， 通过 "2T Trigger" 触发 USB数据卡启用第二数据 发射通道。
本实施例提供的数据接发处理设备， 通过在其中新增数据发射通道， 配 合设置与数据接发处理设备底座对应天线的连接端子， 并通过基带芯片引出 的用于触发新增数据发射通道工作的双发触发接收端子，在 USB数据卡中实 现双发射通道， 增加上行发射增益， 扩大覆盖区域， 降低基站部署成本。 如图 1 所示， 本实施例还提供一种数据接发处理设备底座 2, 包括两条 第二天线 21 , 第二天线 21上设置有用于与数据接发处理设备 1的第一天线 连接的第二天线连接端子；数据接发处理设备底座 2还包括双发触发模块 22, 双发触发模块 22上设置有用于为数据接发处理设备 1提供双发触发信号的双 发触发端子。 双发触发模块 22即为图中所示的 "2T Trigger" , 当数据接发 处理设备 1插入数据接发处理设备底座 2后， 数据接发处理设备 1 中从 BB 引出的双发触发接收端子与双发触发模块 22上的双发触发端子连接，双发触 发模块 22向 BB发送双发触发信号， 指示数据接发处理设备 1启动新增的第 二数据发射通道。 具体地为可以釆用一个单片机检测 USB电路， 当 USB数 据卡插入数据接发处理设备底座之后， "2T Trigger" 检测到 USB信号后触 发单双发切换；还可以釆用电流脉冲方案， 即当 USB数据卡插入数据接发处 理设备底座之后， "2T Trigger" 检测到 USB信号， 然后主动向 USB数据卡 发射一串脉冲码流， BB12检测 USB脉冲码流触发单双发切换， 硬件实现可 以通过小型的 IC集成电路实现； 另外还可以釆用探针方式， BB12通用 10口 接口（General-Purpose 10 ports; 简称： GPI0)检测是否连接底座等。
数据接发处理设备底座 2还包括一个用于供数据接发处理设备 1插入的 插入接口，例如本实施例中釆用 USB接口方式， "USB Connector" 27为 USB 数据卡提供插入接口。
本实施例提供的数据接发处理设备底座， 在数据接发处理设备插入时为 数据接发处理设备提供指示使用新增数据发射通道的双发触发信号或触发数 据接发处理设备产生双触发信号， 配合数据接发处理设备实现 2T2R, 以便增 强数据卡的增加上行发射增益， 扩大覆盖区域， 并可以降低基站部署成本。
如图 2所示， 本实施例提供的数据接发处理系统包括数据接发处理设备 1和数据接发处理设备底座 2,数据接发处理设备 1包括串接的射频收发器模 块即 RF11和基带芯片处理模块即 BB12, 和与 RF11连接的两路第一数据接 收通道和第一数据发射通道， 以及设置于两条第一天线与所述两路第一数据 接收通道和所述第一数据发射通道之间的两个第一接发转换模块 14, 第一接 发转换模块 14与 RF11之间还设置有第二数据发射通道； 第一接发转换模块 14上设置有与数据接发处理设备底座 2连接的第一天线连接端子， BB12上 设置有用于与数据接发处理设备底座 2连接、 触发所述第二数据发射通道工 作的双发触发接收端子； 所述第二数据发射通道从 RF11 至第一接发转换模 块 14包括串接的平衡转换器（Balun )、带通滤波器（ BPF )、功率放大器（ PA ) 和低通滤波器（LPF ) 。
数据接发处理设备底座 2包括两条第二天线 21 , 第二天线 21上设置有 用于与数据接发处理设备第一天线 13连接的第二天线连接端子；还包括双发 触发模块 22, 双发触发模块 22上设置有用于为数据接发处理设备 1提供双 发触发信号的双发触发端子。
数据接发处理设备 1与数据接发处理设备底座 2之间的连接关系如下， 两个所述第一天线连接端子分别与两个所述第二天线连接端子连接， 所述双 发触发接收端子与所述双发触发端子连接。 本系统中涉及的数据接发处理设 备和数据接发处理设备底座可以分别釆用上述图 2中实施例提供的数据接发 处理设备和数据接发处理设备底座， 具体结构不再赘述， 以下通过数据接收 及发射流程详细介绍本系统是如何实现数据卡 2T2R射频设计的。
如图 2所示， 数据接发处理设备 1中的 "SD Card Reader & USB Hug" 是一个支持多 USB口互连和 SD读卡器的器件， 数据接发处理设备 1通过它 与数据接发处理设备底座 2中的 USB连接器（ USB Connector )连接， 同时 数据接发处理设备 1 中基带 BB12芯片引出的一个管脚与数据接发处理设备 底座 2中的 "2T Trigger" 连接并用于检测数据接发处理设备 1是否插入数据 接发处理设备底座 2即 "USB Cradle" 中， 如果是插入 "USB Cradle" 中， 则相应管脚电平抬高，否则是低电平。具体地为可以釆用一个单片机检测 USB 电路， 当 USB数据卡插入数据接发处理设备底座之后， "2T Trigger" 检测 到 USB信号后触发单双发切换； 还可以釆用电流脉冲方案， 即当 USB数据 卡插入数据接发处理设备底座之后， "2T Trigger" 检测到 USB信号， 然后 主动向 USB数据卡发射一串脉冲码流， BB12检测 USB脉冲码流触发单双发 切换，硬件实现可以通过小型的 IC集成电路实现；另外还可以釆用探针方式， BB12通用 10口接口（General-Purpose 10 ports; 简称： GPIO)检测是否连接底 座等。上述实施中， BB12引出的管脚即为上述实施例中描述的双发触发接收 端子。 当数据接发处理设备 1插入数据接发处理设备底座 2中后， 对应的天 线连接端子也将相互连接起来， 数据接发处理系统便可使用数据接发处理底 座中的两天线进行数据的接收和发射。
如图 2所示， 数据接发处理系统中与 RF11连接的从上至下数据通道分 别如下： BB12完成数据的处理后将待发射数据发送给 RF11 , 发射数据按照 图中箭头方向在第一条数据通道上依次经过 "Balun" 、 BPF、 PA和 LPF后， 经过两个 "Swtich" 后沿天线连接端子上传至数据接发处理底座中的天线并 向外界发射， 这是第一条数据发射通道； 另一条数据发射通道是数据经过图 中第四条数据通道依次经过" Balun "、： BPF、PA和 LPF后 ,再经过两个" Swtich" 沿天线连接端子上传至数据接发处理设备底座中的另一条天线后向外界发 射， 这是第二条数据发射通道。 对于数据接收通道， 数据由数据接发处理设 备底座中的一条天线接收后， 下传至数据接发处理设备底座中与连接有数据 接发处理设备天线的 "Swtich" 上， 再经过下一个 "Swtich" , 随后依次经过 BPF和 "Balun" 后传至 RF和 BB中， 实现数据接收， 这是第一条数据接收 通道； 数据由数据接发处理设备底座中的另一条天线接收后， 将数据发送至 第二切换开关 "Swtich" 上， 经过 LNA后达到第三切换开关 "Swtich" , 然 后下传至数据接发处理设备中连接有数据接发处理设备另一条天线的 "Swtich" 上， 再经过下一个 "Swtich" , 随后依次经过 BPF和 "Balun" 后 传至 RF和 BB中， 实现数据接收， 这是第二条数据接收通道； 综上所述， 数 据接发处理设备实现了 2T2R的射频技术。 系统中如图所示， "Airplan mode switch" 为航空模式切换开关， "Micro SD" 为 SD卡连接器， "SPI Flash" 为 SPI接口的 FLASH器件。
本实施例提供的数据接发处理系统， 通过在数据接发处理设备和数据接 发处理设备底座中新增数据发射通道，在数据接发处理设备例如 USB数据卡 中实现双发射通道， 增加上行发射增益， 扩大覆盖区域， 降低基站部署成本。
本发明各实施例提供的两种实现数据卡 2T2R的射频技术的解决方案中， 通过在数据卡或底座中增设第二条数据发射通道， 在数据卡插入底座中后启 动使用完成数据发射；应用 2T2R的射频技术可以在上行链路增益上改善 5dB 增益， 有效解决室内覆盖问题， 降低了基站部署成本。 而且也提供了单双发 射通道切换的机制， 通过基带上的 GPIO实现底座的检测和单双发切换控制。
