* MMCX connectors are micro-miniature connectors with a lock-snap mechanism allowing for 360 degrees rotation and usually have a 50 ohm impedance.

* MMCX connectors are designed for frequency ranges from DC up to 6 GHz and for applications where smallest dimensions have to be achieved.

* It is therefore ideal for applications where board height is limited, including applications where boards may be stacked. As such it is being widely used in many cellular telecommunications and wireless LAN applications.
