MMCX


The MMCX connectors incorporate a 'snap on' latching action for ease of connection with an excellent RF-performance. An additional advantage is their small physical size which is 50% of the standard MCX connector.

This connector range is suitable for the standard ranges of flexible and semi-rigid cables and is also available in PCB and panel mount versions.

The characteristic impedance of the MMCX coaxial connectors is 50 ohm.

MMCX coaxial connectors meet the specification of CECC 22340.
