MMCX series micro-miniature connectors are a smaller version of the MCX and utilize a snap coupling. They are suitable for use up to 6 GHz. The impedance is controlled at 50 ohms. 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 surface mount technology (SMT). Solder and crimp techniques are used to terminate this series to cables. Typical applications include portable instruments and personal communication equipment.
