MMCX Connectors are 45% smaller than the SMB, Developed during the 1990s, is one of the smallest
and Micro-miniature RF coaxial connectors. MMCX series was designed to have snap-on mating, are
available for rf cables, PCB type and SMT type.
MMCX gets low RF leakage from the nonslotting 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), MMCX Connector is still the standard for wireless and PCS applications.
