FMA series RF connector, a new quick-lock series, which is developed based SMA series but with new snap-on connection mechanism related to other self-lock connectors. With the same interfaces as SMA series, FMA series has the same high performances and reliability but does not require the coupling not torque. It offers easier, faster and safer connection than the ZASS and SMA series due to the quick-lock mechanism. Application frequency up to 6 GHz, FMA series is a cost-saving solution for the demands of communications, widely used in cellular base-station, networks and test equipment. FMA series is a patent product and, 100% compatible with QMA series produced by other manufacturers.
