What are the advantages and disadvantages of MMCX connectors?

Time:2019-04-26

The MMCX connector is a coaxial RF connector that was developed in the 1990s and uses a snap-in connection to rotate 360 degrees. Usually its characteristic impedance is 50 ohms. The MMCX connector is commonly found on the antenna interface on a PC's wireless PC card, and on the GPS communication antenna jacks of some PDAs and GPS navigation devices. On some of the in-ear headphones, the MMCX interface is also used to replace the data cable.


The MMCX connector is a push-in connector that is 50 ohms and can be mounted to semi-rigid and flexible coaxial cables. The MMCX connector is 7 mm from the top of the connector to the mating surface and the center stylus is typically 4 mm OD. The MMCX is designed for smaller cables. 0.047, 0.085 (2.1 mm) semi-rigid and RG-316, RG-174. The cutoff frequency of the MMCX is typically about 6 GHz.

MMCX connectors are smaller in size than MCX and cost more. The disadvantage is that there are not many cable types to choose from, and because it is a push-in connection, it is easy to be ejected.
