MMCX microminiature RF connectors are suitable for 50 ohm applications and provide repeatable electronic performance from DC to 6 GHz. The snap-on mating design offers low RF leakage and ease of assembly in dense packaging layouts. The MMCX series is one of the smallest Lighthorse Technologies currently offers, allowing for usage in space critical applications. MMCX type connectors are lightweight, compact and reliable.

Typical applications for MMCX connectors are PCMCIA cards and other small hand-held communications devices.
