MMCX Connector Series

All MMCX Connector

MMCX Plug Connector

MMCX Jack Connector



The MMCX coaxial connector was developed in the 1990’s with a lock-snap mechanism allowing for 360 degrees rotation enabling flexibility in PCB layouts. MMCX connectors conform to the European CECC 22000 specification.

The special lock-snap coupling design also helps to reduce the RF leakage at the joints of the connector.

MMCX connector have a 50 ohm impedance and offer broadband capability from 0 to 6 GHz.
MMCX connector are used in many different applications like GPS tracking, GSM cellular, WLAN equipments, but the most commonly seen on Wi-Fi PCMCIA cards as antenna connectors.
