MCX
The MCX series of miniature connectors utilizes a snap coupling and is suitable for use up to 6 GHz. The impedance is controlled at 50 Ω. 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 and surface mount technology (SMD). Solder and crimp techniques are used to terminate this series to cables. Because of their small size, these connectors have applications in small instruments and communication equipment.
