摘　　要：隔离度为合路器的关键指标,控制驻波、杂散及阻塞干扰的要求共同决定了系统合路的隔离度指标。结合LTE系统邻频的特点,详细研究并确定了LTE邻频系统合路对隔离度的要求,并通过实验验证了该指标满足3GPP要求,隔离度要求的降低减少了合路需要的隔离带宽,节省了宝贵的频谱资源。Isolation is the key metric of the combiner. The requirements of the control of voltage standing wave ratio, spurious emission and blocking interference jointly determine the isolation of the system combination. According to the characteristics of the adjacent channel of LTE system, the requirements on isolation of the combination of LTE adjacent channel system were investigated and determined. Experiments verified that the metric satisfies the requirement of 3GPP. The reduced requirements on isolation decreases the isolation bandwidth required by the combination and saves the precious spectrum resources.
