为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对 实施例或现有技术描述中所需要使用的附图作一简单地介绍, 显而易见 地, 下面描述中的附图是本发明的一些实施例, 对于本领域普通技术人员 来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附 图。 图 1为本发明提供的输出信号功率的提升装置实施例一的结构示意图; 图 2为本发明提供的输出信号功率的提升装置实施例二的结构示意图; 图 3为本发明提供的输出信号功率范围的提升装置的应用示意图; 图 4为本发明提供的输出信号功率的提升设备实施例一的结构示意图; 图 5为本发明提供的输出信号功率的提升设备实施例二的结构示意图; 图 6为本发明提供的输出信号功率的提升方法实施例一的流程示意图; 图 7为本发明提供的输出信号功率的提升方法实施例二的流程示意图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 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清楚、 完整地描 述, 显然,所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提 下所获得的所有其他实施例, 都属于本发明保护的范围。
为了能够更好的适应微波通信的发展, 用户希望无论是在进行长距离 通信还是进行短距离通信, 微波通信设备都能够保证用户较好的服务质 量; 一般的, 用户在进行长距离通信时, 微波通信设备的输出功率较大, 当用户在进行短距离通信时, 微波通信设备的输出功率较小。 因此, 为了 能够给用户提供更好的服务质量, 一般都是针对不同的通信场景, 采用不 同的微波通信设备。 这主要是由于微波通信设备输出功率的动态范围不 够, 即当用户进行长距离通信时, 微波通信设备提供大功率范围, 但是当 用户进行短距离通信时, 微波通信设备若继续为用户提供大功率输出, 则 会带来系统能量浪费; 或者当用户进行短距离通信时, 微波通信设备提供 小功率输出, 但是当用户由短距离通信变为长距离通信时, 微波通信设备 此时提供的功率就难以确保用户的通信质量。
故微波通信设备的输出功率范围若足够大, 就可以同时兼容用户的长 距离通信和短距离通信, 确保用户的通信质量。
图 1为本发明提供的输出信号功率范围的提升装置实施例一的结构示 意图, 该装置可以设置于微波通信设备中, 该装置可以为 0DU。 如图 1所 示, 该装置包括: 判断模块 10、 处理模块 11、 第一触发生成模块 12、 第 二触发生成模块 13 以及输出模块 14; 其中, 判断模块 10, 用于判断待输 出信号的功率位于第一功率区间或第二功率区间; 其中, 所述待输出信号为 满足用户功率需求的信号; 处理模块 11, 用于对所述装置的输入信号进行第 一功率衰减, 并将衰减后的输入信号按照预设功率分配比例分为第一功率信 号和第二功率信号; 第一触发生成模块 12, 用于若上述判断模块 10判断待 输出信号的功率位于第一功率区间, 则触发关闭第二功率信号所在的第二通 道, 并对第一功率信号进行第一处理后, 生成待输出信号; 第二触发生成模 块 13, 用于若上述判断模块 10判断待输出信号的功率位于第二功率区间, 则触发关闭第一功率信号所在的第一通道, 并对第二功率信号进行第二处理 后, 生成待输出信号; 输出模块 14, 用于输出上述待输出信号。
具体的, 当用户需要微波通信设备输出满足其功率要求的信号时, 这 个信号为待输出信号, 判断模块 10 首先会判断该待输出信号的功率位于 第一功率区间还是第二功率区间, 这里的第一功率区间和第二功率区间可 以部分重叠, 也可以不重叠; 在判断模块 10进行功率判断之后, 处理模 块 11 对该装置的输入信号进行相应的第一功率衰减, 这里第一功率衰减 的数值可以由待输出信号的功率确定; 并且, 处理模块 11 将衰减后的输 入信号按照预设的功率分配比例划分为第一功率信号和第二功率信号。
当上述判断模块 10判断得到上述待输出信号的功率位于第一功率区 间, 则第一触发生成模块 12触发关闭第二功率信号所在的第二通道, 并 对第一功率信号进行第一处理, 生成满足用户功率需求的待输出信号并输 出; 这里对第一功率信号进行第一处理, 可以包括对第一功率信号的再次 衰减、 功率放大等处理; 当上述判断模块 10判断得到上述待输出信号的 功率位于第二功率区间, 则第二触发生成模块 13 触发关闭第一功率信号 所在的第一通道, 并对第二功率信号进行第二处理, 生成满足用户功率需 求的待输出信号并输出, 这里对第二功率信号进行第二处理, 可以包括对 第二功率信号的功率放大等处理。
随着用户功率需求的不同(用户会要求输出不同大小的功率的信号), 上述装置会输出不同功率的信号。 例如: 这里假设第一功率区间为 [0dBm,25dBm],第二功率区间为 [-20dBm, OdBm] , 此时假设用户希望输出 12dBm_24dBm范围内的信号, 则 该装置会利用判断模块 10判断该些待输出信号的功率位于哪一个功率区 间。 根据判断, 该些待输出信号的功率位于第一区间内, 则处理模块 1 1 此时对该装置的输入信号进行第一功率衰减, 至于对该装置的输入信号的 功率衰减多少, 是可以通过处理模块 1 1 对输入信号的功率大小、 待输出 信号的功率大小以及功率分配比例进行综合考虑确定的, 也就是说当输入 信号经过第一功率衰减后, 并经过预设功率比例分配至第一通道的信号功 率在经过第一处理后, 就可以输出用户想要的功率的信号。 并且, 在处理 模块 1 1 将输入信号分配至第一通道和第二通道之后, 第一触发生成模块 12此时会触发关闭第二通道, 实现两个通道的能量隔离。 最后, 该装置就 可以输出 12dBm-24dBm范围内的信号。
假设用户此时还需要输出 -lOdBm-OdBm范围内的信号, 同样的, 该装 置会利用判断模块 10判断该些待输出信号的功率位于哪一个功率区间。 根据判断, 该些待输出信号的功率位于第二区间内, 则处理模块 1 1 此时 对该装置的输入信号进行衰减, 至于对该装置的输入信号衰减多少, 也是 可以通过处理模块 1 1 对输入信号的功率大小、 待输出信号的功率大小以 及功率分配比例进行综合考虑确定的, 也就是说当输入信号经过此次衰减 后, 并经过预设功率比例分配至第二通道的信号功率在经过第二处理后, 就可以输出用户想要的功率的信号。 并且, 在处理模块 1 1 将输入信号分 配至第一通道和第二通道之后, 第二触发生成模块 13 此时会触发关闭第 一通道, 实现第一通道和第二通道的能量隔离。 最后该装置就可以输出 -10dBm-0dBm范围内的信号。
但是现有技术中, 当用户希望输出 12dBm-24dBm范围内的信号, 现有 技术是可以满足用户要求的, 但是当用户希望微波通信设备还可以输出 -l OdBm-OdBm范围内的信号, 由于现有技术中缺少第二功率区间和第二通 道的处理分支, 则就不能输出 -lOdBm-OdBm范围内的信号。
本发明实施例提供一种输出信号功率范围的提升装置, 通过判断模块判 断用户要求输出的待输出信号的功率位于第一功率区间或第二功率区间, 处 理模块对所述装置的输入信号进行第一功率衰减后按照预设功率分配比例分 为第一功率信号和第二功率信号; 并在判断模块判断待输出信号的功率位于 第一功率区间时,第一触发生成模块触发关闭第二功率信号所在的第二通道, 并对第一功率信号进行第一处理后, 生成待输出信号并输出; 当判断模块判 断待输出信号的功率位于第二功率区间, 第二触发生成模块触发关闭第一功 率信号所在的第一通道, 并对第二功率信号进行第二处理后, 生成待输出信 号并输出, 从而使得 0DU可以满足用户不同的功率需求进而输出不同功率的 信号, 使得 0DU输出信号的功率范围变大。
图 2为本发明提供的输出信号功率范围的提升装置实施例二的结构示 意图, 在图 1所示实施例的基础上, 上述处理模块 11用于根据待输出信号 的功率、 所述装置的输入信号的功率以及预设功率分配比例确定第一功率衰 减的值; 并根据所述第一功率衰减的值对所述装置的输入信号进行第一功率 衰减。
具体的, 当用户所要求的输出信号的功率不同时, 则上述装置中的处理 模块 11对输入信号的衰减是不同的。上述第一功率衰减的值由待输出信号的 功率、 预设功率分配的比例以及上述装置的输入信号的功率大小确定。
在上述图 2所示装置实施例的基础上, 进一步地, 上述第一触发生成模 块 12可以包括: 第一触发关闭单元 120, 用于触发关闭所述第二通道; 衰减 单元 121, 用于对所述第一功率信号进行第二功率衰减, 生成第三功率信号; 第一放大单元 122, 用于对所述第三功率信号进行放大。
具体的, 当判断模块 10判断待输出信号的功率位于第一功率区间, 则处理模块 11通过触发第一衰减单元 121对上述输入信号进行第一功率 衰减后, 通过预设比例的功率分配将衰减后的输入信号的功率一分为二, 分别输入至第一通道和第二通道; 此时, 第一触发关闭单元 120触发关闭 上述第二通道以实现能量隔离; 之后通过衰减单元 121对输入至第一通道 的第一功率信号进行第二功率衰减, 从而生成第三功率信号, 这里的第二 衰减的值可以由上述待输出信号的功率、 输入信号的功率、 预设功率分配比 例以及第一功率衰减的值确定。 最后通过第一放大单元 122对第三功率信号 进行放大, 从而得到满足用户功率需求的待输出信号。
本发明实施例提供一种输出信号功率范围的提升装置, 通过判断模块判 断用户要求输出的待输出信号的功率位于第一功率区间或第二功率区间, 处 理模块对所述装置的输入信号进行功率衰减后按照预设分配比例分为第一功 率信号和第二功率信号; 并在判断模块判断待输出信号的功率位于第一功率 区间时, 第一触发生成模块触发关闭第二功率信号所在的第二通道, 并对第 一功率信号进行第一处理后, 生成待输出信号并输出; 当判断模块判断待输 出信号的功率位于第二功率区间, 第二触发生成模块触发关闭第一功率信号 所在的第一通道, 并对第二功率信号进行第二处理后, 生成待输出信号并输 出, 从而使得 0DU可以满足用户不同的功率需求进而输出不同功率的信号, 使得 0DU输出信号的功率范围变大。 另一方面, 本发明实施例提供的装置实 现了长距离通信和短距离通信的 0DU输出功率的兼容。
进一步地, 在上述图 2所示实施例的基础上, 上述装置还可以包括检波 模块 15, 用于在上述第一放大单元 122对所述第三功率信号进行放大之后, 对放大后的所述第三功率信号进行检波, 获取检波电压; 调节模块 16, 用于 根据所述检波电压调节所述第一功率衰减的值和所述第二功率衰减的值。
具体的, 本实施例中涉及的检波电压对应的实际是该装置输出的待输出 信号的功率,即本实施例的装置可以通过检波模块 15输出的检波电压获知实 际输出的待输出信号功率的大小, 若实际输出的待输出信号功率与用户所要 求的信号功率有偏差,则通过调节模块 16可以适当调节上述第一功率衰减的 值和第二功率衰减的值, 即形成一个闭环反馈, 使得待输出信号的功率与用 户所要求的信号功率的误差变小。
进一步地, 在上述图 2所示实施例的基础上, 上述第二触发生成模块 13 可以包括: 第二触发关闭单元 130, 用于触发关闭所述第一通道; 第二放大 单元 131, 用于对所述第二功率信号进行放大。
具体的, 当判断模块 10判断待输出信号的功率位于第二功率区间, 则处理模块 11通过触发第一衰减单元 121对上述输入信号进行第一功率 衰减后, 通过预设比例的功率分配将衰减后的输入信号的功率一分为二, 分别输入至第一通道和第二通道; 此时, 第二触发关闭单元 130触发关闭 上述第一通道以实现能量隔离; 之后对第二通道上的第二功率信号进行放 大并输出。
图 3为本发明提供的输出信号功率范围的提升装置的应用示意图, 需 要说明的是, 这里仅是举例说明, 实际上本发明实施例中的提升装置可以 通过不同的电路来实现, 本发明实施例对此不作限制。
如图 3所示, 该电路前端是第一 VVA和滤波器, 图 3中两条平行的微 带线构成了一个定向耦合器, 其作用是将经过第一 VVA衰减后的信号按照 预设的功率分配比例一分为二, 一部分分配至该电路中的第一功率分支, 该第一功率分支相当于上述的第一通道, 其包括第二 VVA、 PA和一检波二 极管, 并且第二 VVA相当于本发明实施例中的衰减单元 121 ; 另一部分分 配至第二功率分支, 该第二功率分支相当于上述的第二通道, 包括一小功 率放大器。
上述第一 VVA和定向耦合器相当于本发明实施例中的处理模块 1 1 ;第 二 VVA相当于本发明实施例中的衰减单元 121, PA相当于本发明实施例中 的第一放大单元 122, 小功率放大器相当于本发明实施例中的第二放大单 元 131, 检波二极管相当于本发明实施例中的检波模块 15, 波导相当于本 发明实施例中的输出模块 14 ;其余未对应起来的模块或单元的功能可以是 装置在运行软件时由底层软件进行处理的。
当用户要求该电路输出某一个功率的信号, 此时, 整个电路可以由相 应的软件控制, 即判断用户所要求输出的信号的功率以及输入信号功率的 大小, 通过软件命令给图 3中的第一 VVA和第二 VVA配置相应的衰减值; 输入信号进入第一 VVA进行第一功率衰减, 然后经过滤波器滤波, 定向耦 合器将滤波后的输入信号按照预设的功率分配比例一分为二, 分为第一功 率信号和第二功率信号; 其中, 第一功率信号(可以为大功率范围的信号) 分配至第一功率分支, 第二功率信号分配至第二功率分支。 当用户要求该 电路输出的信号 (即上述的待输出信号) 为一个大功率的信号, 则关闭该 电路的第二功率分支, 由第一功率分支对第一功率信号进行处理; 若用户 要求该电路输出信号为一个小功率的信号, 则关闭该电路的第一功率分 支, 由第二功率分支对第二功率信号进行处理。 需要注意的是, 这里的大 功率信号或小功率信号是相对而言的, 由第一功率区间的大小和第二功率 区间的大小决定待输出信号的功率是大功率信号还是小功率信号。
需要说明的是, 上述的定向耦合器还可以用功分器或其他具有功率分 配功能的器件替代, 相应的, 整个电路结构也会有变化, 但是仍然会有第 一功率分支和第二功率分支。 并且由于第二功率分支处理的是小功率的信 号, 因此对小功率放大器的要求较低, 相应的成本也会降低; 本发明实施 例中加入了第二功率分支来使得该装置输出另一功率范围内的功率, 降低 了对原有 PA的增益要求, 也就降低了对 PA厂家的依赖性。
本发明实施例提供一种输出信号功率范围的提升装置, 通过判断模块判 断用户要求输出的待输出信号的功率位于第一功率区间或第二功率区间, 处 理模块对所述装置的输入信号进行功率衰减后按照预设分配比例分为第一功 率信号和第二功率信号; 并在判断模块判断待输出信号的功率位于第一功率 区间时, 第一触发生成模块触发关闭第二功率信号所在的第二通道, 并对第 一功率信号进行第一处理后, 生成待输出信号并输出; 当判断模块判断待输 出信号的功率位于第二功率区间, 第二触发生成模块触发关闭第一功率信号 所在的第一通道, 并对第二功率信号进行第二处理后, 生成待输出信号并输 出, 从而使得 0DU可以满足用户不同的功率需求进而输出不同功率的信号, 使得 0DU输出信号的功率范围变大。 另一方面, 本发明实施例提供的装置实 现了长距离通信和短距离通信时 0DU输出功率的兼容。
图 4为本发明提供的输出信号功率范围的提升设备实施例一的结构示意 图, 该设备可以设置于微波通信设备中, 该设备可以为 0DU。 如图 4所示, 该设备包括: 处理器 20、 衰减器 21、 功率分配器 22和发送器 23 ; 其中, 处 理器 20, 用于判断待输出信号的功率位于第一功率区间或第二功率区间; 其 中, 上述待输出信号为满足用户功率需求的信号; 衰减器 21, 用于对该设备 的输入信号进行第一功率衰减; 功率分配器 22, 用于将衰减后的输入信号按 照预设功率分配比例分为第一功率信号和第二功率信号;上述处理器 20还用 于若待输出信号的功率位于第一功率区间, 则触发关闭第二功率信号所在的 第二通道, 并对第一功率信号进行第一处理后, 生成待输出信号; 还用于若 待输出信号的功率位于第二功率区间, 则触发关闭第一功率信号所在的第一 通道, 并对第二功率信号进行第二处理后, 生成待输出信号; 发送器 23, 用 于输出上述待输出信号。
具体的, 当用户需要微波通信设备输出满足其功率要求的信号时, 这 个信号为待输出信号, 处理器 20 首先会判断该待输出信号的功率位于第 一功率区间还是第二功率区间, 这里的第一功率区间和第二功率区间可以 部分重叠, 也可以不重叠; 在处理器 20进行功率判断之后, 衰减器 21对 该设备的输入信号进行相应的第一功率衰减, 这里第一功率衰减的数值可 以由待输出信号的功率确定; 之后, 功率分配器 22将衰减后的输入信号 按照预设的功率分配比例划分为第一功率信号和第二功率信号。
当上述处理器 20判断得到上述待输出信号的功率位于第一功率区间, 则触发关闭第二功率信号所在的第二通道, 并对第一功率信号进行第一处 理, 生成满足用户功率需求的待输出信号并输出; 这里对第一功率信号进 行第一处理, 可以包括对第一功率信号的再次衰减、 功率放大等处理; 当 上述处理器 20判断得到上述待输出信号的功率位于第二功率区间, 则触 发关闭第一功率信号所在的第一通道, 并对第二功率信号进行第二处理, 生成满足用户功率需求的待输出信号并输出, 这里对第二功率信号进行第 二处理, 可以包括对第二功率信号的功率放大等处理; 。
随着用户功率需求的不同(用户会要求输出不同大小的功率的信号), 上述设备会输出不同功率的信号, 进而可以提升输出信号的功率范围。 此 处可以参见装置实施例中的例子。

具体的, 当用户所要求的输出信号的功率不同时, 则上述设备中的衰减 器 21对输入信号的衰减是不同的。上述第一功率衰减的值由待输出信号的功 率、 预设功率分配的比例以及上述设备的输入信号的功率大小确定。
进一步地, 上述处理器 20具体用于触发关闭所述第二通道; 并对所述第 一功率信号进行第二功率衰减, 生成第三功率信号; 并对所述第三功率信号 进行放大。

进一步地, 参照图 5, 在上述图 4所示实施例的基础上, 该设备还包括 检波器 24, 用于对放大后的所述第三功率信号进行检波, 获取检波电压; 则 上述处理器 20 还用于根据所述检波电压调节所述第一功率衰减的值和所述 第二功率衰减的值。
具体的, 本实施例中涉及的检波电压对应的实际是该设备输出的待输出 信号的功率, 即本实施例的设备可以通过检波电压获知实际输出的待输出信 号功率的大小, 若实际输出的待输出信号功率与用户所要求的信号功率有偏 差, 则可以适当调节上述第一功率衰减的值和第二功率衰减的值, 即形成一 个闭环反馈, 使得待输出信号的功率与用户所要求的信号功率的误差变小。
进一步地, 上述处理器 20具体用于触发关闭所述第一通道, 并对所述第 二功率信号进行放大。
