MMCX Connectors or Micro-Miniature CoaXial connectors are snap-on coupling connectors that operate up to 6 GHz. These connectors are a miniature version of MCX RF connectors. The MMCX connectors are standardized under IEC 61169-52 and European CECC 22000 specification.

The MMCX connector was originally developed in the 1990s by Huber+Suhner, developer of the original MCX connector. It is suitable for GPS, antennas, modems, base stations and Wi-Fi applications.
