Cluster connector is a connector that uses multiple coaxial sealed cluster cables, integrating all connectors in a single housing. The purpose is to replace the traditional nine connectors with two connectors, or reduce the number of connectors and rf cables by seven. The cluster connector greatly reduces the point of failure and improves the electrical performance and reliability of products. For the system construction to achieve space saving, cost saving, saving assembly time, improve efficiency. Cluster connector is widely used in multi-array antenna and RRU products or systems in 5G industry.
