RF Coaxial Connectors | MMCX (GJB618A / MIL-C-39012)

MMCX Series RF Coaxial Connector

The MMCX series is a micro-miniature snap-on RF coaxial connector with an industry-standard interface widely used for antenna connections on compact wireless devices. It operates at 50 Ω from DC to 6 GHz with VSWR ≤ 1.3 and 500 mating cycles, and is built to GJB618A (MIL-C-39012) and CECC 22340. Its small footprint and 360° rotating coupling suit tight enclosures.
