Micro Miniature Connector aka. MMCX is one of the smallest design of RF connector line with 50 Ohm impedance and up to DC 6 GHz usage. By incorporating a lock-snap mechanism, it allows easy latching and high flexibility on PCB layouts.
Cross RF offers a range of MMCX connectors that are applicable to various applications including UT series Semi-Rigid or Semi-Flexible, RG/LMR Flexible cable assembly, and PCB surface mount.
