MMCX
The MMCX series of micro-miniature connectors is a smaller version of the MCX and also utilizes a snap coupling. They are suitable for use up to 6 GHz. The impedance is controlled at 50 Ωs. Connector designs are available for flexible, conformable and semi-rigid cables. Styles are available for mounting to printed circuit boards using thru-hole soldering, press-fit nd surface mount technology (SMT). Solder and rimp techniques are used to terminate this series to cables. Because of their small size, these connectors can be used in the smallest of instruments as well as personal communication equipment.
