2 SMK Connectors General Description These high-performance SMK (2.92 mm) connectors feature maximum VSWR for cable connectors of 1.15:1 from DC to 18 GHz, and 1.3:1 from 18 to 40 GHz. The maximum VSWR for receptacles and adapters is 1.15:1 from DC to 18 GHz, and 1.25:1 from 18 to 40 GHz. frequency than SM connectors. The internal design is optimized using state-of-the-art Electromagnetic Finite Element The use of an air dielectric also allows for a smaller internal body diameter than SM connectors. This thick wall design increases outer-conductor contact area at the interface for more reliable electrical performance and higher mechanical strength than SM connectors. in (spark plug) connectors are available for use with hermetic seals or accessory pins with diameters of.009,.012,.015, and.020 inches. The standard hermetic seals match your application requirements. These connectors are machined to exacting tolerances and the highest quality standards on modern CNC turning centers, and assembly is tightly controlled and monitored to ensure peak consistency of performance from unit to unit.
