It integrates the two major functions of splitter for signal equalization and combiner for signal merging. It can flexibly switch working modes according to network system requirements, either evenly dividing a single RF input signal into multiple output signals or combining multiple co-frequency and different-frequency RF signals into a single unified output. With the characteristics of compact structure, stable impedance, low loss and strong compatibility, rf splitter combiner breaks the application limitations of traditional single-function RF devices and has become a universal core component in wireless communication, RF testing, intelligent Internet of Things, security monitoring, military electronics and other fields. With the gradual upgrading of modern RF systems toward integration, diversification and scenarization, different working environments, networking modes and equipment types have significantly different performance requirements for RF splitting and combining devices. Multi-scenario adaptability has become a core standard for evaluating the comprehensive quality of rf splitter combiner. Taking multi-scenario application as the core perspective, combined with multiple dimensions of performance adaptation, working condition adaptation, engineering implementation and operation and maintenance application, this paper comprehensively analyzes the technical characteristics, scenario adaptation advantages and industrial application value of rf splitter combiner.
