2.2-5 type Low PIM Connectors

Description

The 2.2-5 RF coaxial connector is a compact, high-performance 50Ω interconnect system standardized per IEC 61169-66. As a miniaturized evolution of the 4.3-10 interface, it reduces footprint by approximately 53% while retaining excellent electrical and mechanical stability. It supports low-loss RF cables up to 1/2 inch and delivers reliable signal transmission with outstanding passive intermodulation (PIM) performance. Available in threaded and push‑pull coupling versions, it enables blind‑mate installation and is widely used in compact high‑frequency RF systems.

Applications

Small cells, micro base stations, and macro base station RF modules

Distributed Antenna Systems (DAS) and in‑building coverage

4G/5G mobile communication equipment and radio units
