What are MMCX connectors?

MMCX (Micro-Miniature Coaxial) connectors are compact coaxial connectors commonly used in portable electronics, wireless communication devices, and RF modules. They offer quick, tool-free connections in space-limited applications.

MMCX connectors are smaller than traditional coaxial connectors like SMA or BNC, making them ideal for compact electronic devices where size and weight are critical. Despite their small size, they provide good electrical performance and reliable signal transmission.

MMCX connectors are typically used with coaxial cables terminated with MMCX connectors on each end. These cables carry RF signals with minimal loss and interference, ensuring reliable communication between devices.

MMCX cables are kept relatively short to minimise signal loss and maintain integrity, ranging from a few inches to several feet based on the application and signal requirements.

MMCX connectors support various standards, including GSM (900 MHz, 1800 MHz), CDMA (800 MHz, 1900 MHz), LTE (700 MHz, 800 MHz, 1800 MHz, 2600 MHz), and Wi-Fi (2.4 GHz, 5 GHz). This versatility ensures compatibility and efficient signal transmission.

MMCX connectors offer a compact and reliable solution for connecting RF devices in space-limited applications. They provide ease of use and high performance in a small form factor, enhancing connectivity in portable electronics and wireless communication devices.
