[MMCXConnector MMCX-Connectors] are 50 Ohm [CoaxialCable coaxial cable] connectors designed for frequencies up to 6 GHz. "MMCX" stands for "!MicroMate-CoaX", or "!MicroMate-C". The [MMCXConnector MMCX-Connector] was designed in the early 1990's as the smaller brother of the [MCXConnector MCX-Connector]. It is around 45% smaller and lighter than an [SMBConnector SMB-Connectors], and similar in design. The [MMCXConnector MMCX-Connector] has snap-on mating, and can be rotated 360-degrees while mated, and while in-used. The [MMCXConnector MMCX] benifits over the [MCXConnector MCX] in that it provides a slot-less interface to minimise leakage, and increase its durability. Its small size and low weight make it perfect for mobile applications. Many [PCMCIA] [WLAN Wireless LAN] cards use the [MMCXConnector MMCX-Connector], or a slightly modified version called a [RPMMCXConnector Reverse-Polarity MMCX-Connector].
