Using 4.3/10.0 MiniDIN Connectors?

Mini-DIN Products

ClearComm Technologies now offers “Mini-DIN” connectors, 4.1-9.5 DIN, on our Low PIM products high performance requirements of demanding cellular base stations, distributed antenna systems (DAS) and small cell applications.

The 4.3/10.0  MiniDIN connectors have been designed to match the performance of the 7-16 DIN connectors, but with smaller dimensions comparable to the N-Type connector. The smaller screw-on size and weather resistance allows design-and-installation flexibility for medium to high power indoor/outdoor applications. The 4.3/10.0 DIN connectors also offer low VSWR and low PIM (Passive Intermodulation) for frequencies up to 3 GHz.

These low PIM Mini-DIN connectors are available on our Hybrids, Terminations, Cuplers, DAS Interface (POI) Trays, Combiner Trays, and Low PIM jumper cables. Other connectors available include N-Type, 7-16 DIN, and SMA connectors.

Please contact the factory for the latest pricing and availability.
