MMCX

MMCX SERIES- Micro-Miniature Coaxial Connector
 
1. The MMCX series is also called MicroMateTM. Developed in the 1990's, it is a RF coaxial connectors similar to MCX but smaller.
 
2. MMCX is a micro-miniature connector series with a lock-snap mechanism allowing for 360 degrees rotation enabling flexibility in PCB layouts.
 
3.

The micromate family of products is a 6 GHz 50 Ω interconnect system. A range of connectors are available including surface mount, edge card, and cable connectors.
