Specifications
MMCX FEMALE Connector
MMCX Family
MMCX (Micro-Miniature Coaxial) is one of the smallest RF connectors in common use, featuring a snap-lock mechanism rated to 6 GHz. Its tiny size makes it essential for embedded WiFi and Bluetooth modules, wearable devices, hearing aids, and any RF assembly where board space is extremely constrained. It is the standard interface on most M.2 WiFi cards.
Typical Applications
M.2 WiFi cards, Bluetooth modules, wearable devices, embedded wireless modules, surface-mount PCB assemblies.
Gender & Polarity Note
Check the product datasheet for gender and polarity details. RF connectors are available in male (pin), female (socket), and reverse-polarity (RP) variants.
Frequently Asked Questions
What frequency range does the MMCX FEMALE connector support?
MMCX connectors are rated DC – 6 GHz. The effective upper frequency of a cable assembly is limited by the lowest-rated component — either the cable or the connector. Always verify both are within spec for your target frequency.
How many times can a MMCX connector be mated and unmated?
MMCX FEMALE connectors are rated for approximately 500 mating cycles. Exceeding this can cause wear on the contact surfaces, increasing insertion loss and VSWR. For applications with very frequent connects and disconnects, consider a connector rated for higher cycle counts.
What torque should I use to tighten a MMCX connector?
Use a torque wrench and follow the connector manufacturer's recommended torque specification. Hand-tight plus a quarter turn is a safe starting point for most push-on connectors.
Are the MMCX connectors on CoaxRF assemblies weatherproof?
Our standard cable assemblies use high-quality connectors suitable for most indoor and sheltered outdoor applications. For fully weatherproof outdoor installations, we recommend applying self-amalgamating tape over the connector junction to prevent moisture ingress.
Do CoaxRF cables with MMCX FEMALE connectors ship assembled and tested?
Yes. Every cable assembly — including those terminated with MMCX FEMALE connectors — is hand-assembled and continuity tested before shipping. Cables ship free within the US from our US facility.
