RF Connectors

Product Overview

MCX & MMCX Series RF Connectors

Aptiv Interconnect's MCX and MMCX RF connectors offer compact, high-performance solutions for space-constrained applications. Both series feature a user-friendly snap-on coupling and operate up to 6 GHz. They are ideal for wireless communication, GPS, automotive, and portable electronics. The MMCX series is even smaller than the MCX, providing greater design flexibility.
