The MMCX series of micro-miniature connectors is a small version of the MCX and also utilises a snap coupling. They are suitable for use up to 6GHz and impedance is controlled at 50ohm.
Designs are available for flexible, conformable and semi-rigid cables and styles are available for mounting to printed circuit boards using through-hole soldering, press-fit and Surface Mount Technology (SMT). Solder and crimp termination is offered and because of their small size, these connectors can be used in the smallest of instruments as well as personal communication equipment.
