MMCX Micorminiature Connectors

MMCX45% smaller than the SMB, the  MMCX is one of the smallest RF connectors available. Developed during the 1990s, the MMCX series was designed for applications with severe space constraints;particularly where Printed Circuit Boards are stacked tightly together.

Employing a very reliable snap-on interface, the MMCX gets low RF leakage from the non-slotting of its outer contact and it maintains solid electronic performance from DC-6 GHz. Though increasingly being replaced by smaller connectors, like the U.FL (MHF), the MMCX is still the standard for wireless and PCS applications.
