Coupling Mechanism
Interface Standards
The Micro-Miniature CoaXial (MMCX) is a miniaturised version of the MCX RF connector and features snap-on coupling. The series is only 2.4 mm in diameter, ideal for lightweight and space-limited applications. MMCX has the same inner and outer contact interface dimensions as SMB but 45% smaller. The connector utilises a slot-less design to minimise RF leakage, and has been standardised under IEC 61169-52 specification.
History
The connector was developed in the 1990s presumably by Huber+Suhner who developed the original MCX connector.
Applications
MMCX connectors are widely used in GPS, modems, and Wi-Fi hardware due to their low cost and good broadband performance DC to 6 GHz, covering most RF applications.
Variations
Also available in a 75 Ω variant.
