Amphenol RF SMB SMB Connectors Description (R) The SMB name derives from SubMiniature B (the second subminiature design). Developed in the 1960's, this sub miniature interface has snap-on coupling. Amphenol's SMB connectors conform to the requirements of MIL-C-39012, and the interface is in compliance with MIL-STD348. Available in 50 and 75 , the SMB provides broadband capability through 10 GHz with a snap-on connector design and utilizes die cast components on non-critical areas to provide a low-cost solution. 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. 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.
