The SMB (Sub-Miniature version B) connector is a quick-lock mating miniature connector that operates up to 4 GHz in frequency. The SMB interface features a snap-on coupling mechanism and is available in 50-ohm configurations.
SMB connectors are smaller than SMA connectors. However, these connectors are not ideal for harsh environmental conditions, as they are not robust as SMA connectors.
Available in 50 Ohm and 75 Ohm configurations, the SMB connectors are built in accordance with MIL-C-39012, IEC 60169-10, and CECC 22130 interface standards.
