SMB (SubMiniature version B) connectors are coaxial RF connectors developed in the 1960s. SMB connectors are smaller than SMA connectors.
They feature a snap-on coupling and are available in either 50 Ω or 75 Ω impedance. They offer excellent electrical performance from DC to 4 GHz.
An SMB jack has a male centre pin, whilst an SMB plug has a female basket.
Connectors 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)
SSMB
The SSMB connector is a small version of the standard SMB connector with a 'snap-on' coupling.[1][2]
- Impedance: 50 Ohm
- Operating frequency: DC-12,4 GHz
