摘　　要：针对中国联通和中国电信LTE室内分布系统邻频合路的特点,分析合路器关键的隔离度和插入损耗指标,突破了3GPP及常规合路场景指标的限制,降低了隔离带宽的要求,并放宽了插入损耗的要求。然后,利用LTE系统保护带作为合路器滤波器的过渡带,从而实现了邻频系统无隔离邻频合路。Firstly,the key requirements of isolation and insertion loss for combiner were studied,with considering the characteristic of LTE adjacent frequency system of China Unicom and China Telecom. The requirements for both of them are relaxed,which break the general requirement from 3 GPP standards and ordinary combination scenarios. Then,the protection bandwidth of LTE systems were used as the transition band of combiner＇s filter. Finally,the combination of adjacent frequency systems without frequency isolation was realized.
