Cinch SMK Series, Plug SMA Connector, 50Ω, Solder Termination, Straight Body

The Johnson 2.92mm Series Connector provides an excellent solution for demanding applications requiring high frequency transmission.
Although similar to the SMA interface, a smaller internal body diameter (2.92mm) and air dielectric provide a higher cutoff frequency and other
key advantages

Superior electrical performance to 40 GHz
Female contacts have a unique three-slot construction
Mating interface control provides consistent electrical performance
