RP-MMCX Connectors

RP-MMCX Connectors

The MMCX (Micro-Miniature Coaxial) connector series is a micro-miniature version of the MCX. It is a 50 ohm impedance interface with broadband capability of DC to 6 GHz and secure, fast and easy snap-on/snap-off coupling. MMCX connectors have a smaller footprint than the MCX series, and are available in a wide array of configurations.

Like the MCX, the MMCX series conforms to the European CECC 22000 specification.
