本发明的实施例三涉及一种天馈适配装置 100, 如图 1所示， 包括： 第一接口 111 , 第二接口 110, 电压转换器 140, 电容 120, 第一电感 131 和第二电感 130。
电压转换器 140, —端通过第一电感 131连接第一接口 111 , 另一端通过第 二电感 130连接第二接口 110;
电容 120, 电耦合于第一接口 111与第二接口 110之间， 与电压转换器 140 并联。
上述与电压转换器 140相连的第一电感 131 , 用于隔离交流电信号， 也可以 通过多个并联或串联的第一电感替换。 上述与电压转换器 140相连的第二电感 130, 用于隔离交流电信号， 也可以通过多个并联或串联的第二电感替换。 上述 电容 120,用于隔离直流电信号，也可以通过多个并联的电容或串联的电容替换， 其中至少一个电容可以是分布参数电容。
上述装置的工作原理如下：
第二接口 110接收电信号， 该电信号可以是射频信号 （交流电信号）和直 流电信号的混合信号； 电容 120、 第二电感 130将上述射频信号和直流电信号分 离开， 射频信号经电容 120传输至第一接口 111 , 直流电信号经过第二电感 130 进入电压转换器 140, 电压转换器可以根据具体需求， 对该直流信号进行直流- 直流电压转换， 经过转换后的直流电信号的电压可以高于或低于原直流电信号 的电压， 该转换后的直流电信号经过第一电感 131输出至第一接口 111 , 第一接 口 111合并来自 120的射频信号和来自第一电感 131的直流电信号， 并输出合 并后的信号。
上述电容 120可以为分布参数电容， 上述电压转换器 140可以是定参数直 流 -直流电压转换器或参数可调直流 -直流电压转换器。
在实际应用中， 本发明的实施例三所描述的天馈适配装置 100 的第二接口 110可以连接基站接口或通过馈线连接基站接口（如射频接口），其第一接口 111 可以通过馈线连接天馈设备。 该装置通过在馈线通道上获取直流电信号， 对该 直流电信号的电压进行转换后， 再经馈线传输给天馈设备， 可以解决基站系统 升级或替换中遇到的天馈模块电源不兼容的问题， 由于其结构筒单， 成本低廉， 安装方便， 大大降低了基站系统的改造升级成本。
本发明的实施例四涉及一种天馈适配装置 200, 如图 2所示， 包括： 第一接口 211 , 第二接口 210, 电压转换器 240, 电容 220, 第一电感 231 和第二电感 230;
上述部件的连接关系与实施例三中所描述的天馈适配装置相似， 区别在于 还包括：
直流单向器件 250,与第二电感 230串联于所述电压转换器 240与所述第二 接口 210之间， 用于控制电流流向。
第三接口 212, 由直流单向器件 250与所述电压转换器 240之间引出， 用于 连接电源模块。
直流单向器件 250可以采用二极管， 上述电源模块可以是基站中一个模块， 也可以是基站外的独立供电模块， 该电源模块可以用来为天馈设备提供直流电 源。
上述与电压转换器 240相连的第一电感 231 , 用于隔离交流电信号， 也可以 通过多个并联或串联的第一电感替换； 上述与电压转换器 240相连的第二电感 230, 用于隔离交流电信号， 也可以通过多个并联或串联的第二电感替换， 当为 多个第二电感串联时， 直流单向器件 250与该多个第二电感串联， 当为多个第 二电感并联时， 直流单向器件 250与该多个并联后的第二电感串联。； 上述电容 220, 用于隔离直流电信号， 也可以通过多个并联的电容或串联的电容替换， 其 中至少一个电容可以是分布参数电容。
如果第二接口 210接收的信号为射频信号 （交流电信号）和直流电信号的 混合信号， 上述装置的工作原理如下：
第二接口 210接收电信号。 电容 220、 第二电感 230将该电信号中的射频信 号和直流信号分离开， 射频信号经电容 220传输至第一接口 211 , 直流电信号经 过第二电感 230、 直流单向器件 250, 进入电压转换器 240, 电压转换器 240可 以根据具体需求， 对该直流信号进行直流-直流电压转换， 经过转换后的直流电 信号的电压可以高于或低于原直流电信号的电压， 该转换后的直流电信号经过 第一电感 231输出至第一接口 211 ,第一接口 211合并来自 220的射频信号和来 自第一电感 231的直流电信号， 并输出合并后的信号。
如果第二接口 210接收的信号为射频信号， 上述装置的工作原理如下： 第二接口 210接收该射频信号。该射频信号经电容 220传输至第一接口 211 ; 第三接口 212接收来自电源模块的直流电信号， 由于直流单向器件 250的作用， 该直流电信号不会通过第二电感 230回流至第二接口 210所接设备中， 而是进 入电压转换器 240, 电压转换器 240可以根据具体需求， 对该直流信号进行直流 -直流电压转换， 经过转换后的直流电信号的电压可以高于或低于原直流电信号 的电压， 该转换后的直流电信号经过第一电感 231输出至第一接口 211 , 第一接 口 211合并来自电容 220的射频信号和来自第一电感 231的直流电信号， 并输 出合并后的信号。
上述电容可以为分布参数电容， 如图 3所示， 221为射频信号通道内导体， 222为射频信号通道外导体， 射频信号通道内导体 221被分割为两部分， 形成分 布参数电容， 用来阻止直流电信号通过。
在实际应用中， 本发明的实施例四所描述的天馈适配装置 200 的第二接口 210可以连接基站接口或通过馈线连接基站接口（如射频接口），其第一接口 211 可以通过馈线连接天馈设备， 其第三接口可以连接电源模块， 根据所连接基站 的具体情况， 既可以选择在基站射频接口 （馈线通道的一部分）上获取直流电 信号， 又可以从电源模块（电源模块可以是基站内的一功能模块）取直流电信 号， 将接收到的直流电信号转换电压后再经馈线传输给天馈设备， 解决了基站 系统升级中遇到的天馈模块电源不兼容的问题， 除了具有如实施例三的结构筒 单， 成本低廉， 安装方便， 降低基站系统改造升级成本等优点， 本实施例还可 以满足不同供电模式的基站系统的天馈适配改造， 拓宽了适用该装置的基站类 型。 本发明的实施例五涉及一种带塔放的基站系统， 如图 4所示， 包括： 基站 303, 天馈设备（塔放 302, 天线 301 ), 其中塔放 302为有源设备， 需 要直流供电， 本实施例中， 塔放 302从其连接的馈线上取电。
现有技术中， 当天馈设备的工作电压与基站不匹配时， 由基站 303射频接 口经馈线送往塔放的直流电信号不再满足塔放的工作要求， 会导致塔放工作异 常或故障。
本实施例中， 在基站 303 与馈线之间串联如实施例三中所描述的天馈适配 装置 100, 天馈适配装置 100的一端连接基站 303的射频接口， 接收来自基站 303的电信号， 其中该电信号包括射频信号（交流电信号）和直流电信号， 如实 施例三中所描述的， 天馈适配装置 100 可以分离上述射频信号和直流电信号， 同时根据天馈设备的具体需求， 对该直流信号进行直流-直流电压转换， 并将转 换后的直流电信号与原射频信号合并， 由天馈适配装置 100 的另一端将合并后 的信号通过馈线传输至塔放 302。
当然可以根据具体情况安装多个天馈适配装置， 如有多条馈线连接有需进 行适配的天馈装置时， 可以在每条馈线通道上都安装一个天馈适配装置。
本发明的实施例六涉及一种带电调天线的基站系统， 如图 5所示， 包括： 基站 403, 天馈设备（SBT406, RCU ( Remote Control Unit, 电调天线控制 单元） 405, 天线 401 ), 其中 SBT406、 RCU405为有源设备， 需要直流供电， 本实施例中， SBT406从其连接的馈线上取电， RCU405从 SBT406取电。
现有技术中， 当天馈设备的工作电压与基站不匹配时， 由基站 403射频接 口经馈线送往塔放的直流电信号不再满足 SBT406、 RCU405的工作要求， 会导 致这些设备工作异常或故障。
