Molex 2.2-5 RF Connector System

Molex 2.2-5 RF Connector System is 53% smaller than the 4.3-10 Connector System and is ideal for compact mobile radio applications. These high-frequency connectors feature a robust miniature design offering 100 mating cycle durability. Molex 2.2-5 RF Connectors offer low passive intermodulation (PIM) and an air-dielectric interface that provides superior bandwidth with low insertion loss. Three mating options allow design flexibility without compromising electrical performance.
