SMB Subminiature Connectors 

The SMB was developed in the 1960s out of a need for a SubMiniature connector with a quick connect/disconnect interface. Slightly smaller than SMA.
The SMB's snap-on coupling mechanism makes it a convenient and reliable solution in applications that have space constraints.Found in 50 ohm and 75 ohm versions, SMB operates in frequency ranges up to 4 GHz.
