QMSMA-SMA42-1PS - Coaxial adapter QM-SMA (Quick-Mate) male to SMA female, DC - 18 GHz, precision series

QMSMA-SMA42-1PS Precision Adapter

QM-SMA Male to SMA Female | DC to 18 GHz | Quick-Mate Interface

Fast, Reliable RF Connections Without Threading

The QMSMA-SMA42-1PS combines the speed of a Quick-Mate (QM-SMA) interface with the proven performance of a standard SMA connector. Designed for high-frequency test environments, this adapter ensures secure, repeatable connections—no threading required.

Important Notice: The QM-SMA interface is not part of the QMA series. It is a proprietary quick-mate variant designed for fast push-on connections and is not mechanically compatible with QMA connectors.
