SMB connector

Coaxial RF connector

For SMB surface mount diode package, see DO-214.

SMB (SubMiniature version B) connectors are coaxial RF connectors developed in the 1960s. SMB connectors are smaller than SMA connectors.

Quick Facts Type, Production history ...

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 center pin, while an SMB plug has a female basket.[1][2]

Connectors are available for two SMB cable sizes:

  1. Cable 2.6/50+75 S (3 mm outer / 1.7 mm inner diameter) and
  2. Cable 2/50 S (2.2 mm outer / 1 mm inner diameter)

SSMB-Nano

The SSMB-Nano connector is a small version of the standard SMB connector with a 'snap-on' coupling.[3][4]

  1. Impedance: 50 Ohm
  2. Operating frequency: DC–12.4 GHz
