The
SSMB (Subminiature SMB) RF coaxial connector is a miniature version of the standard SMB connector, developed in 1995 and standardized under IEC 60169-19. It features a snap-on mating interface and is designed for 50-ohm impedance systems. Its compact size and lightweight design make it an ideal choice for applications where space is at a premium but signal integrity cannot be compromised.
