   SMB 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 snapon 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 4GHz. ﹛
 
  The series of SMB products are that one kind push the locking type joining, it has small, light, electric
 performance a fine characteristic easy to use, suitable for joining the coaxial cable of the radion frequency to
 use in the radion equipment and radion frequency loop of the electron tube instrument.

     Features & Benefits
         Broadband performance with low reflection DC to 4 GHz provides low cost connector combined with high
              quality.
        Quick connect/disconnect snap-on mating reduces installation time.
          Various plating options in nickel, gold, and tin lead. Selective plating provides corrosion resistance finish
             as well as good solderability characteristics.
        SMB PCB slide-on plug and jack allows board-to-board mounting with a low insertion force. This is ideal
              for mating a high number of connectors on a pair of PCB's.
