• About MCX Series

MCX micro-miniature connectors provide repeatable performance from DC to 6 GHz. The designs of these devices have taken into consideration the need for size reduction, low weight, durability and reliable performance. The MCX devices enable a 30% space reduction over similar SMB/SMC types. The MCX is available for affixement to industry standard cable and as a printed circuit board device. The snap-on connection feature between devices offers the user ease of assembly in dense packaging layouts. Applications for the MCX are those where size, weight, performance and ease of assembly are the driving considerations to the final design decision. Typically, these include GPS, wireless communications (WLAN and mobile) and automotive.
