对附图的简要说明
附图说明
[0015] 下面结合附图对本发明作进一步说明。
[0016] 图 1为本发明创造所提供的一种合路器结构示意图。
本发明的实施方式
[0017] 如图 1所示, 本实施例提供了一种能实现九种不同制式信号合路的合路器。
[0018] 在本实施例中, 本发明创造在腔体侧壁设置有一个合路信号输出端口 100和六 个供不同制式信号接入的信号输入端口: CDMA信号输入端口 21、 DCS信号输入 端口 31、 LTE1.8G信号输入端口 41、 LTE2.1G信号输入端口 51、 TD-A信号输入 端口 61和 TD-CMCC信号输入端口 71。
[0019] 腔体的内部形成了九个信号腔, 可分别同吋接入九路信号。 九个信号腔分别为 : CDMA信号腔 23、 DCS上行信号腔 313、 DCS下行信号腔 323、 LTE1.8G上行信 号腔 413、 LTE1.8G下行信号腔 423、 LTE2.1G上行信号腔 513、 LTE2.1G下行信号 腔 523、 TD-A信号腔 63和 TD-CMCC信号腔 73, 各个信号腔之间相对独立, 与设 置在腔体侧壁上的六个信号输入端口对应连接。
[0020] 本发明创造的各信号腔分布在以合路信号输出端口 100为圆心、 圆心角大于 90 度且小于 360度的范围内。 各信号输入端口和各信号腔与腔体的相对位置关系不 受到限制。 必要吋, 本发明创造的各信号腔还可以分布在以合路信号输出端口 1 00为圆心、 且圆心角大于 180度且小于 360度的范围内。
[0021] 各信号输入端口一合路信号输出端口 100为圆心, 近似扇状地设置在合路器腔 体的侧壁上, 有利于腔体内部的各信号腔位置的紧凑布局, 能够有效地节省生 产制作的材料和物资, 同吋, 信号腔之间紧凑的安排分布, 能适宜地减小合路 器体积大小, 减轻合路器的重量, 方便本发明创造的运送、 安装和使用。
[0022] 在本实施例中, DCS信号输入端口 31、 LTE1.8G信号输入端口 41和 LTE2.1G信 号输入端口可分别接入相对制式的上、 下行信号。 DCS上行信号腔 313和 DCS下 行信号腔 323相邻设置, 且通过 DCS公共耦合谐振柱 301合路后, 再与 DCS信号输 入端口 31耦合匹配阻抗连接。 LTE1.8G上行信号腔 413和 LTE1.8G下行信号腔 423 相邻设置, 且通过 LTE1.8G公共耦合谐振柱 401合路后, 再与 LTE1.8G信号输入 端口 41进行耦合匹配阻抗连接。 LTE2.1G上行信号腔 513和 LTE2.1G下行信号腔 5 23相邻设置且通过 LTE2.1G公共耦合谐振柱 501合路后, 再与 LTE2.1G信号输入 端口 51进行耦合匹配阻抗连接。
[0023] 而余下的三路信号腔, 包括 CDMA信号腔 23、 TD-A信号腔 63和 TD-CMCC信号 腔 73则通过抽头线的方式, 分别与相对应的信号输入端口和合路信号输出端口 1 00相连。
[0024] 在各信号腔中均分别设有相对应的谐振柱, 且依次排列在相对应的信号输入端 口与合路信号输出端口之间, 每个信号腔内的谐振柱个数在 5至 10根范围内。 由 于谐振柱数量少则带来的损耗小、 抑制差, 而谐振柱数量多则带来的损耗大、 抑制好, 因而谐振柱的数量需要考虑实际的信号处理情况。
[0025] 本实施例中, 更具体的, 对应各信号腔所设置的谐振柱数量如下:
[0026] CDMA信号谐振柱 25为 10根、 DCS上行信号谐振柱 315为 6根、 DCS下行信号谐 振柱 325为 7根、 LTE1.8G上行信号谐振柱 415为 6根、 LTE1.8G下行信号谐振柱 42 5为 7根、 LTE2.1G上行信号谐振柱 515为 7根、 LTE2.1G下行信号谐振柱 525为 5根 、 TD-A信号谐振柱 65为 5根、 TD-CMCC信号谐振柱 75为 6根。
[0027] 在同一信号腔之内、 相邻的谐振柱之间还幵设有耦合窗。 一般情况下, 耦合窗 的位于相邻两谐振柱之间的中间位置。 接入到合路器的各路信号, 在经过各自 信号腔内部的谐振柱与耦合窗谐振耦合传输后过滤掉本身以外的信号, 最终从 合路信号输出端口 100合路输出, 形成各频率带通。
[0028] 为了实现合路信号的输出, 多路信号必须通过公共耦合整合成一路信号。 除了 分别设置在 DCS上、 下行信号腔的 DCS公共耦合谐振柱 301, LTE1.8G上、 下行 信号腔的 LTE1.8G公共耦合谐振柱 401, 和 LTE2.1G上、 下行信号腔的 LTE2.1G公 共耦合谐振柱 501之外, 在合路信号输出端口 100还设有构成分级耦合的 3根公共 耦合谐振柱。 在 DCS上、 下行信号腔和 LTE1.8G上、 下行信号腔的输出端处设有 第一个二级公共耦合谐振柱 102; 在 LTE2.1G上、 下行信号腔和 TD-A信号腔的输 出端处设有第二个二级公共耦合谐振柱 103; —级公共耦合谐振柱 101分别与上 述两个二级公共耦合谐振柱 102/ 103相连接, 一级公共耦合谐振柱 101将经过一 级和二级公共耦合的信号输送到合路信号输出端口 100, 与 CDMA信号、 TD-CM
CC信号整合成合路信号。
上述所有的公共耦合谐振柱均为电容耦合方式合路信号, 使合路器的连接端阻 抗容易匹配, 能够适应大量生产, 有效地降低合路器的装配和调试难度。
