Amphenol® SMB Description The SMB name derives from SubMiniature B (the second subminiature design). The SMB was developed in the 1960’s. SMB is a smaller version of the SMA with snap-on coupling. Amphenol’s SMB connectors conform to the requirements of MIL-C-39012 and their interface is in compliance with MIL-STD-348. Available in 50 & 75 ohm impedance SMB provides broadband capability through 4 GHz with a snap-on connector design and utilizes die cast components on non-critical areas to provide a low cost solution. 50 ohm Coaxial Connectors Specifications Plugs Jacks Bulkhead Receptacles PCB Receptacles Features and 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. 75 ohm Coaxial Connectors • Availability in 50 Ohm, 75 Ohm & High Density 75 Ohm ensures customer a solution to specific applications. 75 ohm High Density Coaxial Connectors • SMB PCB slide-on plug and jack allows board to board mounting with a low insertion force. Ideal for mating a high number of connectors on a pair of PCBs.

SPECIFICATIONS MECHANICAL ELECTRICAL 75 ohm snap-on coupling, per MIL-STD-348 Engagement forces Initial 14 lbs. max. engagement. 75 ohms Frequency range 0-4 GHz with low reflection Voltage rating for RG-188/U cables Sea level: 335 volts Dielectric withstanding voltage 750 VRMS, RG-196 type 1000 VRMS, RG-188 type After 500 matings, 14 lbs. max engagement and disengagement. VSWR straight right angle connectors 735A type 1.25 + .04 f (GHz) 1.35 + .04 f (GHz) 2 lbs. min. disengagement. Contact resistance Center contact: initial, 6.0 milliohms; After environmental, 8.0 70,000 ft: 85 volts • Closed entry contact to prevent "slide-by". Outer contact: initial, 1.0 milliohms; After environmental, 1.5 • Full range of high density SMB connector configurations is available, including end launch, printed circuit board and cable connectors. Braid to body: initial, 1.0 milliohms; After environmental, N/A • Series gives design engineers options in applications where physical space is limited. Mating Impedance Insulation resistance: 1000 megohms min. RF leakage -55 dB min. @ 2 - 3 GHz Insertion loss: straight 0.30 dB @ 1.5 GHz rt. angle 0.60 dB @ 1.5 GHz Connector affixment to cable Braid and jacket: hex crimp.
