SMB connectors feature a quick connect Snap-On coupling and are available either in 50ohm or 75ohm impedance. It offers excellent electrical performance from DC to 4 Ghz. This series of connectors conforms to MIL-C-39012. This version is smaller than SMA connectors. They are used for inter board or assembly connections within equipment.
