Specification

50 ohm 0-4 GHz
SMB connectors are semi-precision, subminiature devices that provide repeatable electrical performance to 4 GHz. The SMB family of connectors provide a means of quick-connect and disconnect through a snap-on type coupling.
Its smaller physical size and snap-on coupling make the SMB an ideal general purpose connector where packaging density, ease of mating/unmating and economy are prerequisites. Crimp, clamp and receptacle types are available in right angle, printed circuit board and straight body styles.
Typical applications for SMB connectors are telecommunications, test equipment, instrumentation and GPS.
