2.92mm (K) Connectors are RF/Microwave coaxial connectors that operate mode-free up to 40 GHz. These connectors are compatible to mate with SMA and 3.5mm connectors. The 2.92mm connectors were originally introduced by Mario Maury in 1974 and then re-introduced by Wiltron in 1984 as the K connector. These connectors are standardized as per IEC 61169-35, and are ideal for high-frequency module and T&M applications.
