SMA Connector Dimensions

SMA connectors feature screw-type coupling. Semi-Rigid cabling extends the frequency range of the device to 18GHz. SMA connectors offer broadband performance with low reflections and constant 50 ohm impedance. These properties, along with minimum attenuation and low VSWR have made the SMA connector extremely popular in the microwave community. LTI SMA connectors are designed to conform to MIL-C-39012 specifications.

SMB Connector Dimensions

SMB RF connectors are semi-precision, subminiature devices that provide repeatable electrical performance from DC to 4 GHz. The SMB family of connectors provides a means of quick connect and disconnect through a snap-on type coupling. This makes them useful in areas that are inaccessible to normal mating action. They are best suited for use with cables in the range of .070" to .120" diameters, such as RG 178, RG 174, RG 316. The series is similar in size to SMC connectors but is generally used at a lower frequency. LTI SMB type connectors are designed to conform to MIL-C-39012 specifications. 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. Typical applications for SMB connectors are telecommunications, test equipment, instrumentation, and GPS.

SSMB Connector Dimensions

SSMB RF connectors are microminiature devices that provide repeatable electrical performance from DC to 3GHz. The standard mating design for SSMB series connectors are similar to SMB and SMC but with size reduced approximately one-third. This makes them ideal for use in confined areas where the use of wrenches is not practical. They are lightweight, easy to connect and disconnect, vibration-proof and highly reliable. They are best suited for use with cables in the range of .070" to .120" diameters, such as RG-178, RG-174, and RG-316. Because of their small-size and tight tolerance, finishes other than gold plating are not recommended. SSMB type connectors have gained wide acceptance and usage in military radio systems, where small size is needed for miniaturization but ruggedness and reliability are very important.
