作者: guanzhizhao 标题: 移动GSM和联通GSM合路问题

移动GSM900 和联通 GSM900 合路现在的一般做法是使用电桥，但使用电桥后就有3dB的损失能不能不使用电桥，而使用同频段合路器？？？（现在GSM基站机柜里面是否也有类似的器件，把不同载频的合路，载频间的频率间隔也是相差很少）望各位能解答我心中疑问

，thank

首先你因该确定天馈系统的权属，会不会有产权问题然后确定当地移动和联通是否同意你将2路信号合路如果以上2条都没有问题，你可以找西门子去买合频模块了，那东西带功放的，我想你可能还要买个机柜

,现在是讨论技术问题哦，那些产权问题，维护问题好说，没问题。按你的意思是不是直接采用机柜里面的模块，那模块是不是能实现同频合路但插损很低（<1dB）,国内有没有类似产品。

还有阿，单单那模块来说是有源还是无源

模块有源,实际上就是合路器和功放的集成，没敢拆过。插损也低,但是我没有测过是不是在1db以下还有你要注意，如果联通和移动的信号都在带内，频点太近一定干扰

这边都用电桥了。

<a href="http://www.c114forum.com/dispuser.asp?id=169851" target="_blank">hobojo00</a> 兄 请教一下，基站里面的合路器的频段特性怎样的，是不是覆盖整个GSM900频段，不分移动和联通（我觉得应该是这样的，国际上是制定的是整个GSM900标准，是一个整体，在中国是分给了移动和联通，只要他们按照规定隔开400k以上就没干扰了）我的理解有没有错呢？

据我所知，是的。但是不排除为运营商订制的可能例如 EGSM 频段的使用

这样的话是不是随便用合路器（合路器GSM各支路频谱特性包含整个GSM频段）就能实现移动GSM 和联通GSM 合路，因为为相同系统只要频点满足要求就不会干扰？？？  或者简单的说，把移动的和联通的端口接起来的就行（前提满足端口阻抗匹配）

其实使用电桥是很好的选择LZ说有3dB的损耗，那是误解了。电桥有4端，合路后有2个输出端，2个端口都承载了功率。传统做法是用负载堵住一个，这样防止信号外泄。如果都用上，不就功率又提升了一倍，最多少了点器件损耗。

问题是用不上啊

白白浪费了3dB，有什么高招把这用上

这设备是用在室外基站的，打算把移动和联通的合气来，但插损太大，而室外对插损和发射功率很敏感，所以要千方百计降低插损

买同频合路器咯满大街都是（呵呵，有点夸张了

还有这器件？？？网上查查先，不好意思，我是信产局的，不是专搞这方面的，对微波器件有点菜啊

二功分分配插损3.1dB, 隔离度仅有20dB,驻波较大,两端口in,一端口out; 3dB电桥损耗相当,隔离度有25dB,驻波一般,但是两端口in,两端口out,多一个输出端口; 同频合路器指标最好,最贵;

有没有同频合路器的资料。我在网上找的都是广告
