SMB Connectors

Johnson / Cinch Connectivity Solutions SMB Connectors feature a wide range of 50Ω and 75Ω SMB Connectors with mounting styles that include board, cable, fixed-length cable, self fixture end launch, subminiature attenuators, and mil-spec attenuators. Johnson / Cinch Connectivity Solution SMB Connectors are available in many cables, plug, and jack types (straight, right angle, bulkhead, mini, and flange). The SMB variant provides broadband capability through 4GHz with a snap-on interface design allowing a fast and reliable connection.
