MMCX Connector Series

The MMCX series is one of Amphenol Connex' smallest RF connector lines and was developed in the 1990's. MMCX is a micro-miniature connector series with a Push-on mechanism allowing for 360 degrees rotation enabling flexibility in PCB layouts. MMCX connectors conform to the European CECC 22000 specification.

The MMCX series of products is a 6 GHz 50 Ω interconnect system. A range of connectors are available including surface mount, end launch, and cable connectors designed for a variety of miniature cable types.
