MMCX connector

MMCX (micro-miniature coaxial) connectors are coaxial RF connectors similar to MCX but smaller.

They conform to the European CECC 22 000 specification.

MMCX connectors have a lock-snap mechanism allowing 360-degree rotation and usually have a 50 Ω impedance.

They offer broadband capability from DC to 6 GHz.

MMCX connectors are most commonly seen on Wi-Fi PCMCIA cards as antenna connectors or as connectors

for external GPSantennas on small devices like PDAs or GPS receivers. They were developed in the 1990s.
