SMB (
SubMiniature version B) connectors are coaxial
RF connectors developed in the 1960s. This version is smaller than
SMA connectors.
They feature a snap-on coupling and are available either in 50 Ω or 75 Ω impedances. They offer excellent electrical performance from DC to 4 GHz.
They are available for two SMB cable sizes:
- Cable 2.6/50+75 S (3 mm outer / 1.7 mm inner diameter) and
- Cable 2/50 S (2.2 mm outer / 1 mm inner diameter)
