It bridges two common RF connector families — the threaded SMA found on test cables and instrument ports, and the snap-on QMA used in high-density panel applications where quick disconnect saves time during reconfiguration or field service. The straight body keeps the cable axis aligned, which matters when routing through a crowded chassis or maintaining a consistent bend radius. Rated for 50 Ohms impedance and a maximum frequency of 6 GHz, this adapter covers the L, S, and lower C bands — typical for cellular infrastructure, Wi-Fi access points, and base station RF front-ends where QMA's snap-on mating reduces installation torque errors compared to a full threaded SMA connection. ## Construction and Mating Durability The center contact is beryllium copper with gold plating — a combination chosen for spring retention and corrosion resistance over repeated connects. ## Sourcing Reality: Obsolete Status No official successor order code is listed. If the design can accommodate a parametric alternative, a current-production SMA-to-QMA adapter from the same TE family would be the cleaner long-term fix, but no direct drop-in replacement is recorded.","metaTitle":"TE Connectivity 1408343-1 SMA to QMA Adapter, 50 Ohm, 6 GHz","metaDescription":"TE 1408343-1 SMA plug to QMA jack adapter, 50 Ohm, DC to 6 GHz, straight, gold-plated beryllium copper contacts.
