本发明实施例提供了第一种多频收发信机， 与天线相连， 其可包括： 至少 一个发射多工器，每一发射多工器包括多条发射路径，每条发射路径用于通过 所述天线对一个频段的信号进行发射； 至少一个接收多工器，每一接收多工器 包括多条接收路径，每条接收路径用于通过所述天线对一个频段的信号进行接 收。
在一些可行的实施方式中， 每一发射多工器包含 N个频段之中每个频段 的发射路径； 每一接收多工器包含所述 N个频段之中每个频段的接收路径， 其中， N为大于或等于 2的正整数。 比如， N可为 3, 3个频段分别可为 1800、 2100和 2600。 如此一来， 每一发射多工器同时包含 1800、 2100、 2600频段的 发射路径， 每一接收多工器同时包含 1800、 2100、 2600频段的接收路径。

下面通过附图和具体的实施例对本发明的第一种多频收发信机的组成结 构进行举例说明。
图 2a为本发明的多频收发信机的一实施例的结构组成示意图。 具体实现 中， 本发明实施例的多频收发信机 2可包括 ml个发射多工器 21和 nl个接收 多工器 22 (其中 ml和 nl为正整数， 为便于后续描述， 图 2a中 ml取值为 2, nl取值为 4 ),每一发射多工器 21和每一接收多工器 22均与天线的一端口（端 口如图 2a中的 ANT1....ANTN, 其中， N为 ml+nl , 当 ml取值为 2, nl取 值为 4时， 图 2a中 N取值为 6 )相连， 以通过天线的不同阵列方向接收或者 发射各频段的射频信号， ml和 nl使得所述多频收发信机 2能实现 mlTnlR(表 示多频收发信机 2能实现 ml路发射， nl路接收） 的架构， 进一步， 如图 2a 所示， 发射多工器 21和接收多工器 22均可为 kl工器， 其中， kl表示所述多 频收发信机 2支持的频段的数量， 比如， kl可取 3或 4或者其他。 具体实现 中， 本发明实施例的多频收发信机所支持的具体频段可根据网络需要而定。 为 便于描述，图 2a中以 kl取值为 3举例，且所述 3个频段分别可为： 1800、 2100 以及 2600。
具体实现中， 本发明实施例的发射多工器 21包括多条发射路径， 每条发 射路径用于通过所述天线对一个频段进行发射， 比如， 当 kl取值为 3 , 且支 持的频段为 1800、 2100以及 2600时， 发射多工器 21包括 3条发射路径， 该 三条发射路径分别对 1800、 2100及 2600三个频段的信号进行发射。所述接收 多工器 22包括多条接收路径， 每条接收路径用于通过所述天线对一个频段进 行接收， 比如， 当 kl取值为 3 , 且支持的频段为 1800、 2100以及 2600时， 接收多工器 22包括 3条接收路径， 该三条接收路径分别接收 1800、 2100及 2600三个频段的信号。 具体实现中， 1800的接收频段通常为 1710-1785的频 率， 1800 的发射频段通常为 1805-1880 的频率， 2100 的接收频段通常为 1920-1980的频率， 2100的发射频段通常为 2110-2170的频率， 2600的接收频 段通常为 2500-2570的频率， 2600的发射频段通常为 2620-2690的频率。
进一步， 图 2b为图 2a的架构的另一种表现方式， 在图 2b中， 将天线通 过天线面来表示， 则图 2b中的每个 " X " 代表 1列天线的两个极化方向， 在 图 2b中天线面下面的小方块分别为天线的端口 ANT1....ANTN。 为了便于描 述，在图 2b中 N取值为 6, kl取值为 3。则图 2b中的 T1表示图 2a中与 ANT1 连接的 3工器的发射接口， T1下面的 3个箭头，表示该 3工器的发射频段（分 布为： 1800TX-2100TX-2600TX ); 图 2b中的 R1表示图 2a中与 ANT2连接 3 工器的接收接口， R1 下面的箭头表示该 3 工器的接收频段 （分布为： 1800RX-2100RX-2600RX );图 2b中的 R2表示图 2a中与 ANT3连接 3工器的 发射接口， R2 下面的箭头表示该 3 工器的发射频段 （分布为： 1800RX-2100RX-2600RX ); 图 2b中的 T2表示图 2a中与 ANT4连接的 3工器 的发射接口， T2 下面的 3 个箭头， 表示该 3 工器的发射频段（分布为： 1800TX-2100TX-2600TX ); 图 2b中的 R3表示图 2a中与 ANT5连接的 3工器 的发射接口， R3 下面的 3 个箭头， 表示该 3 工器的接收频段（分布为： 1800RX-2100RX-2600RX );图 2b中的 R4表示图 2a中与 ANT6连接的 3工器 的发射接口， R4 下面的 3 个箭头， 表示该 3 工器的接收频段（分布为： 1800RX-2100RX-2600RX )„ 需要说明的是， 图 2a和图 2b是以 ml为 2, nl 为 4以及 kl为 3举例形成的 2T4R的多频收发信机的结构， 具体实现中， 根 据 ml、 nl以及 kl取值的不同， 多频收发信机包括的发射多工器和接收多工 器的数量可不同，以及发射多工器和接收多工器具体发射或接收的频段数量也 不同。但图 2a-2b所示实施例体现的是一个将多频率发射和多频率接收通过不 同的多工器完全分离的技术方案。 参见图 2b可知， 由于本发明实施例的多频 收发信机通过不同的多工器将多频段的信号的接收和发射进行了完全分离，这 样在每个多工器上的频段信号之间的间隔就增大了， 比如， 针对 1800、 2100 以及 2600三个频段，具体实现中， 1800的接收频段通常为 1710-1785的频率， 1800的发射频段通常为 1805-1880的频率， 2100的接收频段通常为 1920-1980 的频率， 2100的发射频段通常为 2110-2170的频率， 2600的接收频段通常为 2500-2570的频率， 2600的发射频段通常为 2620-2690的频率。 所以， 当采用 本发明实施例图 2a所示的多频收发信机将收发频段分离之后 , 比现有技术的 将相同频段的收发和不同频段的收发全部整合在一起的方案，收发信机每个多 工器上的频段之间的间距均增大（具体体现为： 图 2b中每个多工器下面的频 段间的间隔比图 lb中大）， 由此， 本发明实施例图 2a所示的多频收发信机对 多工器的收发滤波器通道抑制度要求也就减低了， 并且， 由于同一多工器上发 射的频段或者接收的频段之间的频率间隔拉大，使得多工器的滤波器的腔数可 以减少， 利于多工器小型化， 这样随之而来的插损也减小。 另外， 当将收发进 行隔离之后，对天线的互调要求也降低了， 多频收发信机多天线的性能要求也 就降低了， 进而使用的天线的成本也就降低了。
本发明实施例还提供了第二种多频收发信机， 与天线相连， 其包括多个多 工器， 每个多工器包含： 单条发射路径， 用于通过所述天线对一个频段的信号 进行发射;至少一条接收路径， 每一接收路径用于通过所述天线对一个频段的 信号进行接收。 不难理解， 第二种多频收发信机中包含的每个多工器既包含发 射路径又包含接收路径， 因此这种多工器可称为收发多工器。
在一些可行的实施方式中，所述发射路径所发射的频段与所述至少一条接 收路径中一接收路径所接收的频段相同。 例如， 可在一个多工器内同时设置 1800频段的发射路径和接收路径。 在这种情况下， 该多工器内可仅包含 1800 频段的发射路径和接收路径，也可在该多工器内设置其他频段的接收路径， 例 如 2100频段的接收路径。 本领域的技术人员应当明白， 尽管在该多工器内同 时设置了 1800频段的发射路径和接收路径， 但发射路径与接收路径的频率范 围是不同的， 例如， 1800频段内发射路径的频率范围为 1805-1880, 接收频段 通常为 1710-1785。
在一些可行的实施方式中，所述发射路径所发射的频段不同于所述至少一 条接收路径中任一接收路径所接收的频段。例如，可在一个多工器内设置 1800 频段的发射路径， 同时设置 2100和 2600频段的接收路径。
在一些可行的实施方式中，每一接收路径所接收的频段不同于所述至少一 条接收路径中其他任一接收路径所接收的频段。例如， 可在一个多工器内设置 1800频段的发射路径， 同时为 2100和 2600频段各设置一条接收路径。
在一些可行的实施方式中， 所述多个多工器中至少包含 N个多工器， 在 所述 N个多工器中的每一多工器内， 发射路径所发射的频段为 N个频段其中 之一， 每一接收路径为所述 N个频段其中之一， 每一多工器内发射路径所发 射的频段不同于所述 N个多工器中其他任一多工器中发射路径所发射的频段， 其中， N为大于或等于 2的正整数。 例如， 为实现对 1800、 2100和 2600这 3 个频段的收发， 可设置 3个多工器， 在第一个多工器内设置 1800频段的发射 路径， 以及 2100和 2600频段的接收路径。 在第二个多工器内设置 2100频段 的发射路径，以及 1800和 2600频段的接收路径。在第三个多工器内设置 2600 频段的发射路径， 以及 1800和 2100频段的接收路径。
在一些可行的实施方式中，在所述 N个多工器内，至少包含 M个多工器， 在所述 M个多工器内， 每一多工器包含的接收路径的数量相同， 其中， M为 小于 N的正整数。 例如， 为实现对 1800、 2100和 2600这 3个频段的收发， 可设置 3个多工器， 在第一个多工器内设置 1800频段的发射路径， 以及 2100 和 2600频段的接收路径。在第二个多工器内设置 2100频段的发射路径， 以及 1800和 2600频段的接收路径。 在第三个多工器内设置 2600频段的发射路径， 以及 1800和 2100频段的接收路径。在这种情况下，每个多工器均包含 2条接 收路径。
在一些可行的实施方式中， 在所述 N个多工器内， 至少包含一个多工器， 在该多工器内， 接收路径的数量不同于所述 N个多工器内其他至少一个多工 器内接收路径的数量。例如，为实现对 1800、 2100和 2600这 3个频段的收发， 可设置 3个多工器， 在第一个多工器内设置 1800频段的发射路径， 以及 2100 频段的接收路径。 在第二个多工器内设置 2100 频段的发射路径， 以及 1800 和 2600频段的接收路径。在第三个多工器内设置 2600频段的发射路径， 以及 1800频段的接收路径。
在一些可行的实施方式中， 在所述 N个多工器内， 接收所述 N个频段之 中任一频段的接收路径的总量相同。 例如， 为实现对 1800、 2100和 2600这 3 个频段的收发， 可设置 3个多工器， 在第一个多工器内设置 1800频段的发射 路径， 以及 2100和 2600频段的接收路径。 在第二个多工器内设置 2100频段 的发射路径，以及 1800和 2600频段的接收路径。在第三个多工器内设置 2600 频段的发射路径， 以及 1800和 2100频段的接收路径。 在这种情况下， 在包含 上述 3个多工器的收发信机内， 1800、 2100和 2600频段的接收路径的总量均 为 2条。
在一些可行的实施方式中， 在所述 N个频段中， 至少包含一个频段， 在 所述 N个多工器内接收该频段的接收路径的总量不同于所述 N个多工器内接 收所述 N个频段之中另一频段的接收路径的总量。例如，为实现对 1800、 2100 和 2600这 3个频段的收发， 可设置 3个多工器， 在第一个多工器内设置 1800 频段的发射路径， 以及 2100 频段的接收路径。 在第二个多工器内设置 2100 频段的发射路径， 以及 1800和 2600频段的接收路径。在第三个多工器内设置 2600频段的发射路径， 以及 1800频段的接收路径。 因此， 在包含上述 3个多 工器的收发信机内， 1800的接收路径为 2条， 2100频段的接收路径为 1条， 2600频段的接收路径为 1条。 本领域的技术人员应当明白， 在具体实现过程 中， 可根据具体需要（例如所需支持的频带的数量、 各频带的发射路径和接收 路径的数量 )来设置多频收发信机中收发多工器的数量。
下面通过附图和具体的实施例对本发明的第二种多频收发信机的组成结 构进行举例说明。
图 3a为本发明的多频收发信机的另一实施例的结构组成示意图。 具体实 现中， 本发明实施例的多频收发信机 3可包括 m2个收发多工器 31 (其中 m2 为正整数， 表示了多工器与天线阵列的连接通路数， 为便于后续描述， 图 3a 中 m2 取值为 6 ), 每一收发多工器 31 均与天线的一端口 （图 3a 中的 ANT1....ANTN, 其中， N=m2 )相连， 以通过天线的不同阵列方向接收或者 发射各频段的射频信号， 进一步， 如图 3a所示， 收发多工器 31均可为 k2工 器， 其中， k2表示所述多频收发信机 3支持的所有频段， 比如， k2可取 3或 4或者其他。 具体实现中， 本发明实施例的多频收发信机所支持的具体频段可 根据网络需要而定。 为便于描述， 图 3a中以 k2取值为 3举例， 且所述 3个频 段分别可为： 1800、 2100以及 2600。
具体实现中， 本发明实施例的收发多工器 31可包括单条发射路径， 用于 通过所述天线对一个频段进行发射， 与此同时， 所述收发多工器 31还包括至 少一条接收路径，每一接收路径用于通过所述天线对一个频段进行接收，且在 本实施例中， 所述收发多工器 31接收的频段， 与所述发射的频段为不同频段。 比如， 当 k2取值为 3, 且支持的频段为 1800、 2100以及 2600时， 收发多工 器 31包括用于发射 1800频段的信号的发射路径，还包括接收 2100频段和 2600 频段的信号的接收路径， 或者， 收发多工器 31可包括用于发射 2100频段的信 号的发射路径， 还包括接收 1800频段和 2600频段的信号的接收路径， 或者， 收发多工器 31可包括用于发射 2600频段的信号的发射路径，还包括用于接收 2100频段和 1800频段的信号的接收路径。 具体可参见图 3a, 当 m2取值为 6 时， 所述 6个收发多工器 31可划分为 3个多工器组， 每个多工器组包括 2个 多工器，其中，与天线端口 ANT1连接和与天线端口 ANT4连接的收发多工器 31 为第一组， 第一组收发多 工器 31 的收发频段分布为 ： 2600RX-2100RX-1800TX;与天线端口 ANT2连接和与天线端口 ANT5连接的 收发多工器 31 为第二组， 第二组收发多工器 31 的收发频段分布为： 2600RX-2100TX-1800RX;与天线端口 ANT3连接和与天线端口 ANT6连接的 收发多工器 31 为第三组， 第三组收发多工器 31 的收发频段分布为： 2600TX-1800RX-2100RX。 并且， 在本实施例中， 每个多工器包括的接收路径 的数量相同。 并且， 每个频段的接收路径的总量相同。
进一步， 图 3b为图 3a的架构的另一种表现方式， 在图 3b中， 将天线通 过天线面来表示， 则图 3b中的每个 " X " 代表 1列天线的两个极化方向， 在 图 3b中天线面下面的小方块分别为天线的端口 ANT1....ANTN。 为了便于描 述， 在图 3b中 N取值为 6, k2取值为 3。 则图 3b中的 T/R1表示图 3a中与 ANT1连接的 3工器的收发接口， T/R1下面的 3个箭头，表示该 3工器的收发 频段（分布为： 2600RX-2100RX-1800TX ); 图 3b 中的 T/R2表示图 3a中与 ANT2连接 3工器的收发接口， T/R2下面的箭头表示该 3工器的收发频段（分 布为： 2600RX-2100TX-1800RX ); 图 3b中的 T/R3表示图 3a中与 ANT3连接 3 工器的收发接口， T/R3 下面的箭头表示该 3 工器的收发频段（分布为： 2600TX-1800RX-2100RX ); 图 3b中的 T/R4表示图 3a中与 ANT1连接的 3工 器的收发接口， T/R4下面的 3个箭头， 表示该 3工器的收发频段（分布为： 2600RX-2100RX-1800TX ); 图 3b中的 T/R5表示图 3a中与 ANT2连接 3工器 的收发接口， T/R5 下面的箭头表示该 3 工器的收发频段 （分布为： 2600RX-2100TX- 1800RX ); 图 3b中的 T/R6表示图 3a中与 ANT3连接 3工器 的收发接口， T/R6 下面的箭头表示该 3 工器的收发频段 （分布为： 2600TX-1800RX-2100RX )„ 需要说明的是， 图 3a和图 3b是以 m2为 6, k2 为 3举例的多频收发信机的结构， 具体实现中， 根据 m2和 k2取值的不同多 频收发信机包括的收发多工器的数量可不同 ,以及每个收发多工器具体发射和 接收的频率数量也不同。 但图 3a所示实施例体现的多工器发射频率和接收频 率设置为异频的方式， 增加每个多工器上的频率的间隔， 所以， 当采用本发明 实施例图 3a所示的多频收发信机之后， 比现有技术的将相同频段的收发和不 同频段的收发全部整合在一起的方案，每个多工器上的频段之间的间距均增大 (具体体现为： 图 3b中每个多工器下面的频段间的间隔比图 lb中大）， 由此， 本发明实施例图 3a所示的多频收发信机对多工器的收发滤波器通道抑制度要 求也就减低了， 并且， 由于同一多工器上发射的频段或者接收的频段之间的频 率间隔拉大， 使得多工器的滤波器的腔数可以减少， 利于多工器小型化， 这样 随之而来的插损也减小。 另外， 当将收发进行隔离之后， 对天线的互调要求也 降低了， 多频收发信机多天线的性能要求也就降低了，进而使用的天线的成本 也就降低了。
图 4a为本发明的多频收发信机的另一实施例的结构组成示意图。 具体实 现中， 本发明实施例的多频收发信机 4可包括 m3个收发多工器 41 (其中 m3 为正整数， 表示了多工器与天线阵列的连接通路数， 为便于后续描述， 图 4a 中 m3 取值为 6 ), 每一收发多工器 41 均与天线的一端口 （图 4a 中的 ANT1....ANTN, 其中， N=m3 )相连， 以通过天线的不同阵列方向接收或者 发射各频段的射频信号， 进一步， 如图 4a所示， 收发多工器 41均可为 k3工 器， 其中， k3表示所述多频收发信机 4支持的所有频段， 比如， k3可取 3或 4或者其他。 具体实现中， 本发明实施例的多频收发信机所支持的具体频段可 根据网络需要而定。 为便于描述， 图 4a中以 k3取值为 3举例， 且所述 3个频 段分别可为： 1800、 2100以及 2600。
具体实现中， 本发明实施例的收发多工器 41可包括单条发射路径， 用于 通过所述天线对一个频段进行发射， 与此同时， 所述收发多工器 41还包括至 少一条接收路径， 每一接收路径用于通过所述天线对一个频段进行接收，， 且 在本实施例中， 所述收发多工器 41接收的频段， 包括与所述发射的频段处于 相同频段的信号和与所述发射的频段处于不同频段的信号。 比如， 当 k3取值 为 3, 且支持的频段为 1800、 2100以及 2600时， 收发多工器 41可用于发射 1800频段的信号并同时接收 1800频段， 在此基础上还可接收 2100频段和 /或 2600频段的信号， 或者， 收发多工器 41可用于发射 2100频段的信号并同时 接收 2100频段，在此基础上还可接收 1800频段和 /或 2600频段的信号，或者， 收发多工器 41可用于发射 2600频段的信号并同时接收 2600频段， 在此基础 上还可接收 2100频段和 /或 1800频段的信号。 具体可参见图 4a的示例， 当 m3取值为 6时， 所述 6个收发多工器 41可划分为 3个多工器组，每个多工器 组包括 2个多工器，其中，与天线端口 ANT1连接和与天线端口 ANT4连接的 收发多工器 41 为第一组， 第一组收发多工器 41 的收发频段分布为： 2600RX- 1800RX- 1800TX;与天线端口 ANT2连接和与天线端口 ANT5连接的 收发多工器 41 为第二组， 第二组收发多工器 31 的收发频段分布为： 2100RX-2100TX-1800RX;与天线端口 ANT3连接和与天线端口 ANT6连接的 收发多工器 41 为第三组， 第三组收发多工器 41 的收发频段分布为： 2600TX-2600RX-2100RX。
进一步， 图 4b为图 4a的架构的另一种表现方式， 在图 4b中， 将天线通 过天线面来表示， 则图 4b中的每个 " X " 代表 1列天线的两个极化方向， 在 图 4b中天线面下面的小方块分别为天线的端口 ANT1....ANTN。 为了便于描 述， 在图 4b中 N取值为 6, k3取值为 3。 则图 4b中的 T/R1表示图 4a中与 ANT1连接的 3工器的收发接口， T/R1下面的 3个箭头，表示该 3工器的收发 频段（分布为： 2600RX-1800RX-1800TX ); 图 4b 中的 T/R2表示图 4a中与 ANT2连接 3工器的收发接口， T/R2下面的箭头表示该 3工器的收发频段（分 布为： 2100RX-2100TX-1800RX ); 图 4b中的 T/R3表示图 4a中与 ANT3连接 3 工器的收发接口， T/R3 下面的箭头表示该 3 工器的收发频段（分布为： 2600TX-2600RX-2100RX ); 图 4b中的 T/R4表示图 4a中与 ANT1连接的 3工 器的收发接口， T/R4下面的 3个箭头， 表示该 3工器的收发频段（分布为： 2600RX-1800RX-1800TX ); 图 4b中的 T/R5表示图 4a中与 ANT2连接 3工器 的收发接口， T/R5 下面的箭头表示该 3 工器的收发频段 （分布为： 2100RX-2100TX-1800RX ); 图 4b中的 T/R6表示图 4a中与 ANT3连接 3工器 的收发接口， T/R6 下面的箭头表示该 3 工器的收发频段 （分布为： 2600TX-2600RX-2100RX )„ 需要说明的是， 图 4a和图 4b是以 m3为 6, k3 为 3举例的多频收发信机的结构， 具体实现中， 根据 m3和 k3取值的不同多 频收发信机包括的收发多工器的数量可不同 ,以及每个收发多工器具体发射和 接收的频率数量也不同。 但图 4a所示实施例体现的多工器发射频率和接收频 率设置在满足一个频段同频的前提下，接收其他异频的信号， 由此增加每个多 工器上的频率的间隔， 所以， 当采用本发明实施例图 4a所示的多频收发信机 之后， 比现有技术的六工器收发共用的方案，每个多工器上的频段之间的间距 均增大（具体体现为： 图 4b中每个多工器下面的频段间的间隔比图 4b中大）， 由此， 本发明实施例图 4a所示的多频收发信机对多工器的收发滤波器通道抑 制度要求也就减低了， 并且， 由于同一多工器上发射的频段或者接收的频段之 间的频率间隔拉大,使得多工器的滤波器的腔数可以减少，利于多工器小型化， 这样随之而来的插损也减小。 另外， 当将收发进行隔离之后， 对天线的互调要 求也降低了， 多频收发信机多天线的性能要求也就降低了， 进而使用的天线的 成本也就降低了。
相应的， 本发明实施例提供了一种基站， 该基站可包括本发明前述各实施 例的多频收发信机。
总之， 以上所述仅为本发明技术方案的较佳实施例而已， 并非用于限定本 发明的保护范围。凡在本发明的精神和原则之内，所作的任何修改、等同替换、 改进等， 均应包含在本发明的保护范围之内。
